Given numbers are 784, 556, 401, 560

The list of prime factors of all numbers are

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

Prime factors of 556 are 2 x 2 x 139

Prime factors of 401 are 401

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

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

Given numbers are 784, 556, 401, 560

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

Apply this formula for all numbers.

Step1:

LCM(784, 556) = 108976

GCD(784, 556) = ( 784 x 556 ) / 108976

= 784 / 556

= 784

Step2:

LCM(4, 401) = 1604

GCD(4, 401) = ( 4 x 401 ) / 1604

= 4 / 401

= 4

Step3:

LCM(1, 560) = 560

GCD(1, 560) = ( 1 x 560 ) / 560

= 1 / 560

= 1

So, Greatest Common Divisor of 784, 556, 401, 560 is 1
