Given numbers are 420, 163, 781, 946

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 163 are 163

Prime factors of 781 are 11 x 71

Prime factors of 946 are 2 x 11 x 43

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

Given numbers are 420, 163, 781, 946

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

Apply this formula for all numbers.

Step1:

LCM(420, 163) = 68460

GCD(420, 163) = ( 420 x 163 ) / 68460

= 420 / 163

= 420

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 946) = 946

GCD(1, 946) = ( 1 x 946 ) / 946

= 1 / 946

= 1

So, Greatest Common Divisor of 420, 163, 781, 946 is 1
