Given numbers are 764, 156, 360, 221

The list of prime factors of all numbers are

Prime factors of 764 are 2 x 2 x 191

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

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 764, 156, 360, 221

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

Apply this formula for all numbers.

Step1:

LCM(764, 156) = 29796

GCD(764, 156) = ( 764 x 156 ) / 29796

= 764 / 156

= 764

Step2:

LCM(4, 360) = 360

GCD(4, 360) = ( 4 x 360 ) / 360

= 4 / 360

= 4

Step3:

LCM(4, 221) = 884

GCD(4, 221) = ( 4 x 221 ) / 884

= 4 / 221

= 4

So, Greatest Common Divisor of 764, 156, 360, 221 is 1
