Given numbers are 420, 430, 994, 662

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

Apply this formula for all numbers.

Step1:

LCM(420, 430) = 18060

GCD(420, 430) = ( 420 x 430 ) / 18060

= 420 / 430

= 420

Step2:

LCM(10, 994) = 4970

GCD(10, 994) = ( 10 x 994 ) / 4970

= 10 / 994

= 10

Step3:

LCM(2, 662) = 662

GCD(2, 662) = ( 2 x 662 ) / 662

= 2 / 662

= 2

So, Greatest Common Divisor of 420, 430, 994, 662 is 2
