## 7. gcf, hcf, gcd (105; 63) = 21 = 3 × 7: the greatest (highest) common factor ...

• gcf (105; 63) = ? Calculate the greatest (highest) common factor (divisor) of numbers, gcf (hcf, gcd), by two methods: 1) The prime factorization ...

• gcf, hcf, gcd(105; 63)=? The two methods used below to calculate the greatest common factor:  The prime factorization  The Euclidean Algorithm Method 1. The prime factorization: The prime factorization of a number: finding the prime numbers that multiply together to make that number. 105=3×5×7 105 is not a prime number but a composite one. 63=3^2×7 63 is not a prime number but a composite one. * The natural numbers that are only divisible by 1 and themselves are called prime numbers. A prime number has exactly two factors: 1 and itself. * A composite number is a natural number that has at least one other factor than 1 and itself. >> The prime factorization Calculate the greatest(highest) common factor(divisor): Multiply all the common prime factors, taken by their smallest exponents(the smallest powers). The greatest(highest) common factor(divisor), gcf, hcf, gcd(105; 63)=3×7=21 The two numbers have common prime factors. Scroll down for the 2nd method... Method 2. The Euclidean Algorithm: This algorithm involves the process of dividing numbers and calculating the remainders. 'a' and 'b' are the two natural numbers, 'a' >= 'b'. Divide 'a' by 'b' and get the remainder of the operation, 'r'. If 'r'=0, STOP. 'b'=the gcf(hcf, gcd) of 'a' and 'b'. Else: Replace('a' by 'b') and('b' by 'r'). Return to the step above. >> The Euclidean Algorithm Step 1. Divide the larger number by the smaller one: 105÷63=1+42 Step 2. Divide the smaller number by the above operation's remainder: 63÷42=1+21 Step 3. Divide the remainder of the step 1 by the remainder of the step 2: 42÷21=2+0 At this step, the remainder is zero, so we stop: 21 is the number we were looking for - the last non-zero remainder. This is the greatest(highest) common factor(divisor). The greatest(highest) common factor(divisor): gcf, hcf, gcd(105; 63)=21=3×7 The two numbers have common prime factors Why do we need to calculate the greatest common factor? Once you've calculated the greatest common factor of the numerator and the denominator of a fraction, it becomes much easier to fully reduce(simplify) the fraction to the lowest terms(the smallest possible numerator and denominator).
