Given numbers are 671, 508, 780, 221

The list of prime factors of all numbers are

Prime factors of 671 are 11 x 61

Prime factors of 508 are 2 x 2 x 127

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

Prime factors of 221 are 13 x 17

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

Given numbers are 671, 508, 780, 221

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

Apply this formula for all numbers.

Step1:

LCM(671, 508) = 340868

GCD(671, 508) = ( 671 x 508 ) / 340868

= 671 / 508

= 671

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 671, 508, 780, 221 is 1
