Given numbers are 636, 651, 487, 394

The list of prime factors of all numbers are

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

Prime factors of 651 are 3 x 7 x 31

Prime factors of 487 are 487

Prime factors of 394 are 2 x 197

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

Given numbers are 636, 651, 487, 394

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

Apply this formula for all numbers.

Step1:

LCM(636, 651) = 138012

GCD(636, 651) = ( 636 x 651 ) / 138012

= 636 / 651

= 636

Step2:

LCM(3, 487) = 1461

GCD(3, 487) = ( 3 x 487 ) / 1461

= 3 / 487

= 3

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 636, 651, 487, 394 is 1
