Given numbers are 724, 701, 780, 423

The list of prime factors of all numbers are

Prime factors of 724 are 2 x 2 x 181

Prime factors of 701 are 701

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 423 are 3 x 3 x 47

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

Given numbers are 724, 701, 780, 423

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

Apply this formula for all numbers.

Step1:

LCM(724, 701) = 507524

GCD(724, 701) = ( 724 x 701 ) / 507524

= 724 / 701

= 724

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

So, Greatest Common Divisor of 724, 701, 780, 423 is 1
