Given numbers are 934, 780, 31, 840

The list of prime factors of all numbers are

Prime factors of 934 are 2 x 467

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 31 are 31

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

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

Given numbers are 934, 780, 31, 840

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

Apply this formula for all numbers.

Step1:

LCM(934, 780) = 364260

GCD(934, 780) = ( 934 x 780 ) / 364260

= 934 / 780

= 934

Step2:

LCM(2, 31) = 62

GCD(2, 31) = ( 2 x 31 ) / 62

= 2 / 31

= 2

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 934, 780, 31, 840 is 1
