Given numbers are 660, 320, 857, 242

The list of prime factors of all numbers are

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

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 857 are 857

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 660, 320, 857, 242

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

Apply this formula for all numbers.

Step1:

LCM(660, 320) = 10560

GCD(660, 320) = ( 660 x 320 ) / 10560

= 660 / 320

= 660

Step2:

LCM(20, 857) = 17140

GCD(20, 857) = ( 20 x 857 ) / 17140

= 20 / 857

= 20

Step3:

LCM(1, 242) = 242

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

= 1 / 242

= 1

So, Greatest Common Divisor of 660, 320, 857, 242 is 1
