Given numbers are 425, 636, 100, 639

The list of prime factors of all numbers are

Prime factors of 425 are 5 x 5 x 17

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

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 425, 636, 100, 639

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

Apply this formula for all numbers.

Step1:

LCM(425, 636) = 270300

GCD(425, 636) = ( 425 x 636 ) / 270300

= 425 / 636

= 425

Step2:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 425, 636, 100, 639 is 1
