Given numbers are 121, 117, 570, 987

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 117 are 3 x 3 x 13

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 987 are 3 x 7 x 47

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

Given numbers are 121, 117, 570, 987

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

Apply this formula for all numbers.

Step1:

LCM(121, 117) = 14157

GCD(121, 117) = ( 121 x 117 ) / 14157

= 121 / 117

= 121

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

So, Greatest Common Divisor of 121, 117, 570, 987 is 1
