Given numbers are 221, 910, 764, 654

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 910 are 2 x 5 x 7 x 13

Prime factors of 764 are 2 x 2 x 191

Prime factors of 654 are 2 x 3 x 109

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

Given numbers are 221, 910, 764, 654

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

Apply this formula for all numbers.

Step1:

LCM(221, 910) = 15470

GCD(221, 910) = ( 221 x 910 ) / 15470

= 221 / 910

= 221

Step2:

LCM(13, 764) = 9932

GCD(13, 764) = ( 13 x 764 ) / 9932

= 13 / 764

= 13

Step3:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

So, Greatest Common Divisor of 221, 910, 764, 654 is 1
