Given numbers are 556, 253, 840, 560

The list of prime factors of all numbers are

Prime factors of 556 are 2 x 2 x 139

Prime factors of 253 are 11 x 23

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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 556, 253, 840, 560

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

Apply this formula for all numbers.

Step1:

LCM(556, 253) = 140668

GCD(556, 253) = ( 556 x 253 ) / 140668

= 556 / 253

= 556

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 560) = 560

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

= 1 / 560

= 1

So, Greatest Common Divisor of 556, 253, 840, 560 is 1
