Given numbers are 420, 994, 348, 947

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

Apply this formula for all numbers.

Step1:

LCM(420, 994) = 29820

GCD(420, 994) = ( 420 x 994 ) / 29820

= 420 / 994

= 420

Step2:

LCM(14, 348) = 2436

GCD(14, 348) = ( 14 x 348 ) / 2436

= 14 / 348

= 14

Step3:

LCM(2, 947) = 1894

GCD(2, 947) = ( 2 x 947 ) / 1894

= 2 / 947

= 2

So, Greatest Common Divisor of 420, 994, 348, 947 is 1
