Given numbers are 550, 745, 142, 660

The list of prime factors of all numbers are

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

Prime factors of 745 are 5 x 149

Prime factors of 142 are 2 x 71

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 550, 745, 142, 660

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

Apply this formula for all numbers.

Step1:

LCM(550, 745) = 81950

GCD(550, 745) = ( 550 x 745 ) / 81950

= 550 / 745

= 550

Step2:

LCM(5, 142) = 710

GCD(5, 142) = ( 5 x 142 ) / 710

= 5 / 142

= 5

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 550, 745, 142, 660 is 1
