Given numbers are 442, 974, 140, 489

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

Apply this formula for all numbers.

Step1:

LCM(442, 974) = 215254

GCD(442, 974) = ( 442 x 974 ) / 215254

= 442 / 974

= 442

Step2:

LCM(2, 140) = 140

GCD(2, 140) = ( 2 x 140 ) / 140

= 2 / 140

= 2

Step3:

LCM(2, 489) = 978

GCD(2, 489) = ( 2 x 489 ) / 978

= 2 / 489

= 2

So, Greatest Common Divisor of 442, 974, 140, 489 is 1
