Given numbers are 321, 331, 154, 387

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

Prime factors of 331 are 331

Prime factors of 154 are 2 x 7 x 11

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 321, 331, 154, 387

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

Apply this formula for all numbers.

Step1:

LCM(321, 331) = 106251

GCD(321, 331) = ( 321 x 331 ) / 106251

= 321 / 331

= 321

Step2:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

Step3:

LCM(1, 387) = 387

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

= 1 / 387

= 1

So, Greatest Common Divisor of 321, 331, 154, 387 is 1
