Given numbers are 240, 440, 855, 124

The list of prime factors of all numbers are

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 124 are 2 x 2 x 31

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

Given numbers are 240, 440, 855, 124

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

Apply this formula for all numbers.

Step1:

LCM(240, 440) = 2640

GCD(240, 440) = ( 240 x 440 ) / 2640

= 240 / 440

= 240

Step2:

LCM(40, 855) = 6840

GCD(40, 855) = ( 40 x 855 ) / 6840

= 40 / 855

= 40

Step3:

LCM(5, 124) = 620

GCD(5, 124) = ( 5 x 124 ) / 620

= 5 / 124

= 5

So, Greatest Common Divisor of 240, 440, 855, 124 is 1
