Given numbers are 784, 639, 52, 636

The list of prime factors of all numbers are

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

Prime factors of 639 are 3 x 3 x 71

Prime factors of 52 are 2 x 2 x 13

Prime factors of 636 are 2 x 2 x 3 x 53

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

Given numbers are 784, 639, 52, 636

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

Apply this formula for all numbers.

Step1:

LCM(784, 639) = 500976

GCD(784, 639) = ( 784 x 639 ) / 500976

= 784 / 639

= 784

Step2:

LCM(1, 52) = 52

GCD(1, 52) = ( 1 x 52 ) / 52

= 1 / 52

= 1

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 784, 639, 52, 636 is 1
