Given numbers are 157, 340, 648, 653

The list of prime factors of all numbers are

Prime factors of 157 are 157

Prime factors of 340 are 2 x 2 x 5 x 17

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

Prime factors of 653 are 653

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

Given numbers are 157, 340, 648, 653

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

Apply this formula for all numbers.

Step1:

LCM(157, 340) = 53380

GCD(157, 340) = ( 157 x 340 ) / 53380

= 157 / 340

= 157

Step2:

LCM(1, 648) = 648

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

= 1 / 648

= 1

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 157, 340, 648, 653 is 1
