Given numbers are 549, 860, 120, 142

The list of prime factors of all numbers are

Prime factors of 549 are 3 x 3 x 61

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

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 142 are 2 x 71

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

Given numbers are 549, 860, 120, 142

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

Apply this formula for all numbers.

Step1:

LCM(549, 860) = 472140

GCD(549, 860) = ( 549 x 860 ) / 472140

= 549 / 860

= 549

Step2:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

Step3:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 549, 860, 120, 142 is 1
