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

Prime factors of 955 are 5 x 191

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

Given numbers are 171, 456, 980, 955

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

Apply this formula for all numbers.

Step1:

LCM(171, 456) = 1368

GCD(171, 456) = ( 171 x 456 ) / 1368

= 171 / 456

= 171

Step2:

LCM(57, 980) = 55860

GCD(57, 980) = ( 57 x 980 ) / 55860

= 57 / 980

= 57

Step3:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1

So, Greatest Common Divisor of 171, 456, 980, 955 is 1
