Given numbers are 798, 660, 765, 653

The list of prime factors of all numbers are

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 653 are 653

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

Given numbers are 798, 660, 765, 653

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

Apply this formula for all numbers.

Step1:

LCM(798, 660) = 87780

GCD(798, 660) = ( 798 x 660 ) / 87780

= 798 / 660

= 798

Step2:

LCM(6, 765) = 1530

GCD(6, 765) = ( 6 x 765 ) / 1530

= 6 / 765

= 6

Step3:

LCM(3, 653) = 1959

GCD(3, 653) = ( 3 x 653 ) / 1959

= 3 / 653

= 3

So, Greatest Common Divisor of 798, 660, 765, 653 is 1
