Given numbers are 121, 856, 633, 387

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 633 are 3 x 211

Prime factors of 387 are 3 x 3 x 43

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

Given numbers are 121, 856, 633, 387

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

Apply this formula for all numbers.

Step1:

LCM(121, 856) = 103576

GCD(121, 856) = ( 121 x 856 ) / 103576

= 121 / 856

= 121

Step2:

LCM(1, 633) = 633

GCD(1, 633) = ( 1 x 633 ) / 633

= 1 / 633

= 1

Step3:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

So, Greatest Common Divisor of 121, 856, 633, 387 is 1
