Given numbers are 155, 649, 980, 501

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 649 are 11 x 59

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 501 are 3 x 167

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

Given numbers are 155, 649, 980, 501

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

Apply this formula for all numbers.

Step1:

LCM(155, 649) = 100595

GCD(155, 649) = ( 155 x 649 ) / 100595

= 155 / 649

= 155

Step2:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

Step3:

LCM(1, 501) = 501

GCD(1, 501) = ( 1 x 501 ) / 501

= 1 / 501

= 1

So, Greatest Common Divisor of 155, 649, 980, 501 is 1
