Given numbers are 280, 721, 784, 925

The list of prime factors of all numbers are

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

Prime factors of 721 are 7 x 103

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 925 are 5 x 5 x 37

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

Given numbers are 280, 721, 784, 925

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

Apply this formula for all numbers.

Step1:

LCM(280, 721) = 28840

GCD(280, 721) = ( 280 x 721 ) / 28840

= 280 / 721

= 280

Step2:

LCM(7, 784) = 784

GCD(7, 784) = ( 7 x 784 ) / 784

= 7 / 784

= 7

Step3:

LCM(7, 925) = 6475

GCD(7, 925) = ( 7 x 925 ) / 6475

= 7 / 925

= 7

So, Greatest Common Divisor of 280, 721, 784, 925 is 1
