Given numbers are 392, 420, 974, 516

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

Apply this formula for all numbers.

Step1:

LCM(392, 420) = 5880

GCD(392, 420) = ( 392 x 420 ) / 5880

= 392 / 420

= 392

Step2:

LCM(28, 974) = 13636

GCD(28, 974) = ( 28 x 974 ) / 13636

= 28 / 974

= 28

Step3:

LCM(2, 516) = 516

GCD(2, 516) = ( 2 x 516 ) / 516

= 2 / 516

= 2

So, Greatest Common Divisor of 392, 420, 974, 516 is 2
