Given numbers are 777, 717, 774, 221

The list of prime factors of all numbers are

Prime factors of 777 are 3 x 7 x 37

Prime factors of 717 are 3 x 239

Prime factors of 774 are 2 x 3 x 3 x 43

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 777, 717, 774, 221

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

Apply this formula for all numbers.

Step1:

LCM(777, 717) = 185703

GCD(777, 717) = ( 777 x 717 ) / 185703

= 777 / 717

= 777

Step2:

LCM(3, 774) = 774

GCD(3, 774) = ( 3 x 774 ) / 774

= 3 / 774

= 3

Step3:

LCM(3, 221) = 663

GCD(3, 221) = ( 3 x 221 ) / 663

= 3 / 221

= 3

So, Greatest Common Divisor of 777, 717, 774, 221 is 1
