Given numbers are 242, 870, 665, 124

The list of prime factors of all numbers are

Prime factors of 242 are 2 x 11 x 11

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 665 are 5 x 7 x 19

Prime factors of 124 are 2 x 2 x 31

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

Given numbers are 242, 870, 665, 124

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

Apply this formula for all numbers.

Step1:

LCM(242, 870) = 105270

GCD(242, 870) = ( 242 x 870 ) / 105270

= 242 / 870

= 242

Step2:

LCM(2, 665) = 1330

GCD(2, 665) = ( 2 x 665 ) / 1330

= 2 / 665

= 2

Step3:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

So, Greatest Common Divisor of 242, 870, 665, 124 is 1
