Given numbers are 188, 122, 987, 121

The list of prime factors of all numbers are

Prime factors of 188 are 2 x 2 x 47

Prime factors of 122 are 2 x 61

Prime factors of 987 are 3 x 7 x 47

Prime factors of 121 are 11 x 11

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

Given numbers are 188, 122, 987, 121

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

Apply this formula for all numbers.

Step1:

LCM(188, 122) = 11468

GCD(188, 122) = ( 188 x 122 ) / 11468

= 188 / 122

= 188

Step2:

LCM(2, 987) = 1974

GCD(2, 987) = ( 2 x 987 ) / 1974

= 2 / 987

= 2

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 188, 122, 987, 121 is 1
