Given numbers are 142, 120, 639, 550

The list of prime factors of all numbers are

Prime factors of 142 are 2 x 71

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

Prime factors of 639 are 3 x 3 x 71

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 142, 120, 639, 550

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

Apply this formula for all numbers.

Step1:

LCM(142, 120) = 8520

GCD(142, 120) = ( 142 x 120 ) / 8520

= 142 / 120

= 142

Step2:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 142, 120, 639, 550 is 1
