Given numbers are 639, 370, 520, 550

The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 370 are 2 x 5 x 37

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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 639, 370, 520, 550

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

Apply this formula for all numbers.

Step1:

LCM(639, 370) = 236430

GCD(639, 370) = ( 639 x 370 ) / 236430

= 639 / 370

= 639

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 550) = 550

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

= 1 / 550

= 1

So, Greatest Common Divisor of 639, 370, 520, 550 is 1
