Given numbers are 420, 214, 744, 915

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 214 are 2 x 107

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 915 are 3 x 5 x 61

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

Given numbers are 420, 214, 744, 915

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

Apply this formula for all numbers.

Step1:

LCM(420, 214) = 44940

GCD(420, 214) = ( 420 x 214 ) / 44940

= 420 / 214

= 420

Step2:

LCM(2, 744) = 744

GCD(2, 744) = ( 2 x 744 ) / 744

= 2 / 744

= 2

Step3:

LCM(2, 915) = 1830

GCD(2, 915) = ( 2 x 915 ) / 1830

= 2 / 915

= 2

So, Greatest Common Divisor of 420, 214, 744, 915 is 1
