Given numbers are 494, 420, 978, 862

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

Apply this formula for all numbers.

Step1:

LCM(494, 420) = 103740

GCD(494, 420) = ( 494 x 420 ) / 103740

= 494 / 420

= 494

Step2:

LCM(2, 978) = 978

GCD(2, 978) = ( 2 x 978 ) / 978

= 2 / 978

= 2

Step3:

LCM(2, 862) = 862

GCD(2, 862) = ( 2 x 862 ) / 862

= 2 / 862

= 2

So, Greatest Common Divisor of 494, 420, 978, 862 is 2
