Given numbers are 420, 678, 763, 954

The list of prime factors of all numbers are

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

Prime factors of 678 are 2 x 3 x 113

Prime factors of 763 are 7 x 109

Prime factors of 954 are 2 x 3 x 3 x 53

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

Given numbers are 420, 678, 763, 954

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

Apply this formula for all numbers.

Step1:

LCM(420, 678) = 47460

GCD(420, 678) = ( 420 x 678 ) / 47460

= 420 / 678

= 420

Step2:

LCM(6, 763) = 4578

GCD(6, 763) = ( 6 x 763 ) / 4578

= 6 / 763

= 6

Step3:

LCM(1, 954) = 954

GCD(1, 954) = ( 1 x 954 ) / 954

= 1 / 954

= 1

So, Greatest Common Divisor of 420, 678, 763, 954 is 1
