Given numbers are 420, 280, 724, 929

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Prime factors of 724 are 2 x 2 x 181

Prime factors of 929 are 929

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

Given numbers are 420, 280, 724, 929

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

Apply this formula for all numbers.

Step1:

LCM(420, 280) = 840

GCD(420, 280) = ( 420 x 280 ) / 840

= 420 / 280

= 420

Step2:

LCM(140, 724) = 25340

GCD(140, 724) = ( 140 x 724 ) / 25340

= 140 / 724

= 140

Step3:

LCM(4, 929) = 3716

GCD(4, 929) = ( 4 x 929 ) / 3716

= 4 / 929

= 4

So, Greatest Common Divisor of 420, 280, 724, 929 is 1
