Given numbers are 715, 840, 378, 939

The list of prime factors of all numbers are

Prime factors of 715 are 5 x 11 x 13

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 939 are 3 x 313

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

Given numbers are 715, 840, 378, 939

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

Apply this formula for all numbers.

Step1:

LCM(715, 840) = 120120

GCD(715, 840) = ( 715 x 840 ) / 120120

= 715 / 840

= 715

Step2:

LCM(5, 378) = 1890

GCD(5, 378) = ( 5 x 378 ) / 1890

= 5 / 378

= 5

Step3:

LCM(1, 939) = 939

GCD(1, 939) = ( 1 x 939 ) / 939

= 1 / 939

= 1

So, Greatest Common Divisor of 715, 840, 378, 939 is 1
