Given numbers are 372, 420, 865, 308

The list of prime factors of all numbers are

Prime factors of 372 are 2 x 2 x 3 x 31

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

Prime factors of 865 are 5 x 173

Prime factors of 308 are 2 x 2 x 7 x 11

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

Given numbers are 372, 420, 865, 308

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

Apply this formula for all numbers.

Step1:

LCM(372, 420) = 13020

GCD(372, 420) = ( 372 x 420 ) / 13020

= 372 / 420

= 372

Step2:

LCM(12, 865) = 10380

GCD(12, 865) = ( 12 x 865 ) / 10380

= 12 / 865

= 12

Step3:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

So, Greatest Common Divisor of 372, 420, 865, 308 is 1
