Given numbers are 636, 900, 642, 257

The list of prime factors of all numbers are

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

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

Prime factors of 642 are 2 x 3 x 107

Prime factors of 257 are 257

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

Given numbers are 636, 900, 642, 257

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

Apply this formula for all numbers.

Step1:

LCM(636, 900) = 47700

GCD(636, 900) = ( 636 x 900 ) / 47700

= 636 / 900

= 636

Step2:

LCM(12, 642) = 1284

GCD(12, 642) = ( 12 x 642 ) / 1284

= 12 / 642

= 12

Step3:

LCM(6, 257) = 1542

GCD(6, 257) = ( 6 x 257 ) / 1542

= 6 / 257

= 6

So, Greatest Common Divisor of 636, 900, 642, 257 is 1
