Given numbers are 648, 722, 790, 695

The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 722 are 2 x 19 x 19

Prime factors of 790 are 2 x 5 x 79

Prime factors of 695 are 5 x 139

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

Given numbers are 648, 722, 790, 695

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

Apply this formula for all numbers.

Step1:

LCM(648, 722) = 233928

GCD(648, 722) = ( 648 x 722 ) / 233928

= 648 / 722

= 648

Step2:

LCM(2, 790) = 790

GCD(2, 790) = ( 2 x 790 ) / 790

= 2 / 790

= 2

Step3:

LCM(2, 695) = 1390

GCD(2, 695) = ( 2 x 695 ) / 1390

= 2 / 695

= 2

So, Greatest Common Divisor of 648, 722, 790, 695 is 1
