Given numbers are 879, 781, 420, 678

The list of prime factors of all numbers are

Prime factors of 879 are 3 x 293

Prime factors of 781 are 11 x 71

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

Prime factors of 678 are 2 x 3 x 113

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

Given numbers are 879, 781, 420, 678

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

Apply this formula for all numbers.

Step1:

LCM(879, 781) = 686499

GCD(879, 781) = ( 879 x 781 ) / 686499

= 879 / 781

= 879

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

So, Greatest Common Divisor of 879, 781, 420, 678 is 1
