Given numbers are 791, 156, 258, 648

The list of prime factors of all numbers are

Prime factors of 791 are 7 x 113

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 258 are 2 x 3 x 43

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

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

Given numbers are 791, 156, 258, 648

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

Apply this formula for all numbers.

Step1:

LCM(791, 156) = 123396

GCD(791, 156) = ( 791 x 156 ) / 123396

= 791 / 156

= 791

Step2:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 791, 156, 258, 648 is 1
