Given numbers are 665, 550, 640, 158

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

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

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 158 are 2 x 79

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

Given numbers are 665, 550, 640, 158

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

Apply this formula for all numbers.

Step1:

LCM(665, 550) = 73150

GCD(665, 550) = ( 665 x 550 ) / 73150

= 665 / 550

= 665

Step2:

LCM(5, 640) = 640

GCD(5, 640) = ( 5 x 640 ) / 640

= 5 / 640

= 5

Step3:

LCM(5, 158) = 790

GCD(5, 158) = ( 5 x 158 ) / 790

= 5 / 158

= 5

So, Greatest Common Divisor of 665, 550, 640, 158 is 1
