Given numbers are 672, 690, 775, 790

The list of prime factors of all numbers are

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Prime factors of 775 are 5 x 5 x 31

Prime factors of 790 are 2 x 5 x 79

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

Given numbers are 672, 690, 775, 790

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

Apply this formula for all numbers.

Step1:

LCM(672, 690) = 77280

GCD(672, 690) = ( 672 x 690 ) / 77280

= 672 / 690

= 672

Step2:

LCM(6, 775) = 4650

GCD(6, 775) = ( 6 x 775 ) / 4650

= 6 / 775

= 6

Step3:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

So, Greatest Common Divisor of 672, 690, 775, 790 is 1
