Given numbers are 423, 858, 65, 940

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 65 are 5 x 13

Prime factors of 940 are 2 x 2 x 5 x 47

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

Given numbers are 423, 858, 65, 940

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

Apply this formula for all numbers.

Step1:

LCM(423, 858) = 120978

GCD(423, 858) = ( 423 x 858 ) / 120978

= 423 / 858

= 423

Step2:

LCM(3, 65) = 195

GCD(3, 65) = ( 3 x 65 ) / 195

= 3 / 65

= 3

Step3:

LCM(1, 940) = 940

GCD(1, 940) = ( 1 x 940 ) / 940

= 1 / 940

= 1

So, Greatest Common Divisor of 423, 858, 65, 940 is 1
