Given numbers are 155, 600, 578, 660

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 600 are 2 x 2 x 2 x 3 x 5 x 5

Prime factors of 578 are 2 x 17 x 17

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 155, 600, 578, 660

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

Apply this formula for all numbers.

Step1:

LCM(155, 600) = 18600

GCD(155, 600) = ( 155 x 600 ) / 18600

= 155 / 600

= 155

Step2:

LCM(5, 578) = 2890

GCD(5, 578) = ( 5 x 578 ) / 2890

= 5 / 578

= 5

Step3:

LCM(1, 660) = 660

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

= 1 / 660

= 1

So, Greatest Common Divisor of 155, 600, 578, 660 is 1
