Given numbers are 860, 129, 400, 242

The list of prime factors of all numbers are

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 129 are 3 x 43

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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 860, 129, 400, 242

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

Apply this formula for all numbers.

Step1:

LCM(860, 129) = 2580

GCD(860, 129) = ( 860 x 129 ) / 2580

= 860 / 129

= 860

Step2:

LCM(43, 400) = 17200

GCD(43, 400) = ( 43 x 400 ) / 17200

= 43 / 400

= 43

Step3:

LCM(1, 242) = 242

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

= 1 / 242

= 1

So, Greatest Common Divisor of 860, 129, 400, 242 is 1
