Given numbers are 391, 387, 156, 750

The list of prime factors of all numbers are

Prime factors of 391 are 17 x 23

Prime factors of 387 are 3 x 3 x 43

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 750 are 2 x 3 x 5 x 5 x 5

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

Given numbers are 391, 387, 156, 750

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

Apply this formula for all numbers.

Step1:

LCM(391, 387) = 151317

GCD(391, 387) = ( 391 x 387 ) / 151317

= 391 / 387

= 391

Step2:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

Step3:

LCM(1, 750) = 750

GCD(1, 750) = ( 1 x 750 ) / 750

= 1 / 750

= 1

So, Greatest Common Divisor of 391, 387, 156, 750 is 1
