Given numbers are 690, 780, 837, 718

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

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

Prime factors of 837 are 3 x 3 x 3 x 31

Prime factors of 718 are 2 x 359

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

Given numbers are 690, 780, 837, 718

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

Apply this formula for all numbers.

Step1:

LCM(690, 780) = 17940

GCD(690, 780) = ( 690 x 780 ) / 17940

= 690 / 780

= 690

Step2:

LCM(30, 837) = 8370

GCD(30, 837) = ( 30 x 837 ) / 8370

= 30 / 837

= 30

Step3:

LCM(3, 718) = 2154

GCD(3, 718) = ( 3 x 718 ) / 2154

= 3 / 718

= 3

So, Greatest Common Divisor of 690, 780, 837, 718 is 1
