Given numbers are 721, 267, 890, 668

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 267 are 3 x 89

Prime factors of 890 are 2 x 5 x 89

Prime factors of 668 are 2 x 2 x 167

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

Given numbers are 721, 267, 890, 668

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

Apply this formula for all numbers.

Step1:

LCM(721, 267) = 192507

GCD(721, 267) = ( 721 x 267 ) / 192507

= 721 / 267

= 721

Step2:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 721, 267, 890, 668 is 1
