Given numbers are 908, 840, 253, 561

The list of prime factors of all numbers are

Prime factors of 908 are 2 x 2 x 227

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

Prime factors of 253 are 11 x 23

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 908, 840, 253, 561

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

Apply this formula for all numbers.

Step1:

LCM(908, 840) = 190680

GCD(908, 840) = ( 908 x 840 ) / 190680

= 908 / 840

= 908

Step2:

LCM(4, 253) = 1012

GCD(4, 253) = ( 4 x 253 ) / 1012

= 4 / 253

= 4

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 908, 840, 253, 561 is 1
