Given numbers are 636, 654, 261, 644

The list of prime factors of all numbers are

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

Prime factors of 654 are 2 x 3 x 109

Prime factors of 261 are 3 x 3 x 29

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 636, 654, 261, 644

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

Apply this formula for all numbers.

Step1:

LCM(636, 654) = 69324

GCD(636, 654) = ( 636 x 654 ) / 69324

= 636 / 654

= 636

Step2:

LCM(6, 261) = 522

GCD(6, 261) = ( 6 x 261 ) / 522

= 6 / 261

= 6

Step3:

LCM(3, 644) = 1932

GCD(3, 644) = ( 3 x 644 ) / 1932

= 3 / 644

= 3

So, Greatest Common Divisor of 636, 654, 261, 644 is 1
