Given numbers are 721, 824, 678, 911

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 824 are 2 x 2 x 2 x 103

Prime factors of 678 are 2 x 3 x 113

Prime factors of 911 are 911

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

Given numbers are 721, 824, 678, 911

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

Apply this formula for all numbers.

Step1:

LCM(721, 824) = 5768

GCD(721, 824) = ( 721 x 824 ) / 5768

= 721 / 824

= 721

Step2:

LCM(103, 678) = 69834

GCD(103, 678) = ( 103 x 678 ) / 69834

= 103 / 678

= 103

Step3:

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

= 1 / 911

= 1

So, Greatest Common Divisor of 721, 824, 678, 911 is 1
