Given numbers are 402, 280, 568, 721

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 568 are 2 x 2 x 2 x 71

Prime factors of 721 are 7 x 103

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

Given numbers are 402, 280, 568, 721

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

Apply this formula for all numbers.

Step1:

LCM(402, 280) = 56280

GCD(402, 280) = ( 402 x 280 ) / 56280

= 402 / 280

= 402

Step2:

LCM(2, 568) = 568

GCD(2, 568) = ( 2 x 568 ) / 568

= 2 / 568

= 2

Step3:

LCM(2, 721) = 1442

GCD(2, 721) = ( 2 x 721 ) / 1442

= 2 / 721

= 2

So, Greatest Common Divisor of 402, 280, 568, 721 is 1
