Given numbers are 105, 511, 764, 221

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 511 are 7 x 73

Prime factors of 764 are 2 x 2 x 191

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 105, 511, 764, 221

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

Apply this formula for all numbers.

Step1:

LCM(105, 511) = 7665

GCD(105, 511) = ( 105 x 511 ) / 7665

= 105 / 511

= 105

Step2:

LCM(7, 764) = 5348

GCD(7, 764) = ( 7 x 764 ) / 5348

= 7 / 764

= 7

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 105, 511, 764, 221 is 1
