Given numbers are 360, 120, 421, 861

The list of prime factors of all numbers are

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 421 are 421

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 360, 120, 421, 861

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

Apply this formula for all numbers.

Step1:

LCM(360, 120) = 360

GCD(360, 120) = ( 360 x 120 ) / 360

= 360 / 120

= 360

Step2:

LCM(120, 421) = 50520

GCD(120, 421) = ( 120 x 421 ) / 50520

= 120 / 421

= 120

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 360, 120, 421, 861 is 1
