Given numbers are 125, 840, 576, 123

The list of prime factors of all numbers are

Prime factors of 125 are 5 x 5 x 5

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

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 123 are 3 x 41

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

Given numbers are 125, 840, 576, 123

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

Apply this formula for all numbers.

Step1:

LCM(125, 840) = 21000

GCD(125, 840) = ( 125 x 840 ) / 21000

= 125 / 840

= 125

Step2:

LCM(5, 576) = 2880

GCD(5, 576) = ( 5 x 576 ) / 2880

= 5 / 576

= 5

Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 125, 840, 576, 123 is 1
