Given numbers are 405, 861, 942, 910

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 861 are 3 x 7 x 41

Prime factors of 942 are 2 x 3 x 157

Prime factors of 910 are 2 x 5 x 7 x 13

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

Given numbers are 405, 861, 942, 910

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

Apply this formula for all numbers.

Step1:

LCM(405, 861) = 116235

GCD(405, 861) = ( 405 x 861 ) / 116235

= 405 / 861

= 405

Step2:

LCM(3, 942) = 942

GCD(3, 942) = ( 3 x 942 ) / 942

= 3 / 942

= 3

Step3:

LCM(3, 910) = 2730

GCD(3, 910) = ( 3 x 910 ) / 2730

= 3 / 910

= 3

So, Greatest Common Divisor of 405, 861, 942, 910 is 1
