Given numbers are 721, 468, 565, 821

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 468 are 2 x 2 x 3 x 3 x 13

Prime factors of 565 are 5 x 113

Prime factors of 821 are 821

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

Given numbers are 721, 468, 565, 821

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

Apply this formula for all numbers.

Step1:

LCM(721, 468) = 337428

GCD(721, 468) = ( 721 x 468 ) / 337428

= 721 / 468

= 721

Step2:

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

= 1 / 565

= 1

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 721, 468, 565, 821 is 1
