Given numbers are 325, 507, 780, 166

The list of prime factors of all numbers are

Prime factors of 325 are 5 x 5 x 13

Prime factors of 507 are 3 x 13 x 13

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 166 are 2 x 83

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

Given numbers are 325, 507, 780, 166

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

Apply this formula for all numbers.

Step1:

LCM(325, 507) = 12675

GCD(325, 507) = ( 325 x 507 ) / 12675

= 325 / 507

= 325

Step2:

LCM(13, 780) = 780

GCD(13, 780) = ( 13 x 780 ) / 780

= 13 / 780

= 13

Step3:

LCM(13, 166) = 2158

GCD(13, 166) = ( 13 x 166 ) / 2158

= 13 / 166

= 13

So, Greatest Common Divisor of 325, 507, 780, 166 is 1
