Given numbers are 863, 777, 456, 420

The list of prime factors of all numbers are

Prime factors of 863 are 863

Prime factors of 777 are 3 x 7 x 37

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 863, 777, 456, 420

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

Apply this formula for all numbers.

Step1:

LCM(863, 777) = 670551

GCD(863, 777) = ( 863 x 777 ) / 670551

= 863 / 777

= 863

Step2:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 863, 777, 456, 420 is 1
