Given numbers are 157, 768, 680, 242

The list of prime factors of all numbers are

Prime factors of 157 are 157

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 242 are 2 x 11 x 11

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

Given numbers are 157, 768, 680, 242

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

Apply this formula for all numbers.

Step1:

LCM(157, 768) = 120576

GCD(157, 768) = ( 157 x 768 ) / 120576

= 157 / 768

= 157

Step2:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

Step3:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

So, Greatest Common Divisor of 157, 768, 680, 242 is 1
