Given numbers are 742, 777, 690, 873

The list of prime factors of all numbers are

Prime factors of 742 are 2 x 7 x 53

Prime factors of 777 are 3 x 7 x 37

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

Prime factors of 873 are 3 x 3 x 97

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

Given numbers are 742, 777, 690, 873

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

Apply this formula for all numbers.

Step1:

LCM(742, 777) = 82362

GCD(742, 777) = ( 742 x 777 ) / 82362

= 742 / 777

= 742

Step2:

LCM(7, 690) = 4830

GCD(7, 690) = ( 7 x 690 ) / 4830

= 7 / 690

= 7

Step3:

LCM(1, 873) = 873

GCD(1, 873) = ( 1 x 873 ) / 873

= 1 / 873

= 1

So, Greatest Common Divisor of 742, 777, 690, 873 is 1
