Given numbers are 657, 870, 387, 121

The list of prime factors of all numbers are

Prime factors of 657 are 3 x 3 x 73

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 387 are 3 x 3 x 43

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 657, 870, 387, 121

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

Apply this formula for all numbers.

Step1:

LCM(657, 870) = 190530

GCD(657, 870) = ( 657 x 870 ) / 190530

= 657 / 870

= 657

Step2:

LCM(3, 387) = 387

GCD(3, 387) = ( 3 x 387 ) / 387

= 3 / 387

= 3

Step3:

LCM(3, 121) = 363

GCD(3, 121) = ( 3 x 121 ) / 363

= 3 / 121

= 3

So, Greatest Common Divisor of 657, 870, 387, 121 is 1
