Given numbers are 721, 666, 763, 884

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 763 are 7 x 109

Prime factors of 884 are 2 x 2 x 13 x 17

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

Given numbers are 721, 666, 763, 884

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

Apply this formula for all numbers.

Step1:

LCM(721, 666) = 480186

GCD(721, 666) = ( 721 x 666 ) / 480186

= 721 / 666

= 721

Step2:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

Step3:

LCM(1, 884) = 884

GCD(1, 884) = ( 1 x 884 ) / 884

= 1 / 884

= 1

So, Greatest Common Divisor of 721, 666, 763, 884 is 1
