Given numbers are 641, 745, 784, 675

The list of prime factors of all numbers are

Prime factors of 641 are 641

Prime factors of 745 are 5 x 149

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 675 are 3 x 3 x 3 x 5 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 641, 745, 784, 675

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(641, 745) = 477545

GCD(641, 745) = ( 641 x 745 ) / 477545

= 641 / 745

= 641

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

Step3:

LCM(1, 675) = 675

GCD(1, 675) = ( 1 x 675 ) / 675

= 1 / 675

= 1

So, Greatest Common Divisor of 641, 745, 784, 675 is 1
