Given numbers are 740, 420, 838, 939

The list of prime factors of all numbers are

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 838 are 2 x 419

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 740, 420, 838, 939

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

Apply this formula for all numbers.

Step1:

LCM(740, 420) = 15540

GCD(740, 420) = ( 740 x 420 ) / 15540

= 740 / 420

= 740

Step2:

LCM(20, 838) = 8380

GCD(20, 838) = ( 20 x 838 ) / 8380

= 20 / 838

= 20

Step3:

LCM(2, 939) = 1878

GCD(2, 939) = ( 2 x 939 ) / 1878

= 2 / 939

= 2

So, Greatest Common Divisor of 740, 420, 838, 939 is 1
