Given numbers are 255, 157, 407, 861

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 157 are 157

Prime factors of 407 are 11 x 37

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 255, 157, 407, 861

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

Apply this formula for all numbers.

Step1:

LCM(255, 157) = 40035

GCD(255, 157) = ( 255 x 157 ) / 40035

= 255 / 157

= 255

Step2:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

Step3:

LCM(1, 861) = 861

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

= 1 / 861

= 1

So, Greatest Common Divisor of 255, 157, 407, 861 is 1
