Given numbers are 133, 637, 644, 251

The list of prime factors of all numbers are

Prime factors of 133 are 7 x 19

Prime factors of 637 are 7 x 7 x 13

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

Prime factors of 251 are 251

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

Given numbers are 133, 637, 644, 251

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

Apply this formula for all numbers.

Step1:

LCM(133, 637) = 12103

GCD(133, 637) = ( 133 x 637 ) / 12103

= 133 / 637

= 133

Step2:

LCM(7, 644) = 644

GCD(7, 644) = ( 7 x 644 ) / 644

= 7 / 644

= 7

Step3:

LCM(7, 251) = 1757

GCD(7, 251) = ( 7 x 251 ) / 1757

= 7 / 251

= 7

So, Greatest Common Divisor of 133, 637, 644, 251 is 1
