Given numbers are 251, 957, 155, 990

The list of prime factors of all numbers are

Prime factors of 251 are 251

Prime factors of 957 are 3 x 11 x 29

Prime factors of 155 are 5 x 31

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 251, 957, 155, 990

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

Apply this formula for all numbers.

Step1:

LCM(251, 957) = 240207

GCD(251, 957) = ( 251 x 957 ) / 240207

= 251 / 957

= 251

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 251, 957, 155, 990 is 1
