Given numbers are 282, 662, 686, 645

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

Apply this formula for all numbers.

Step1:

LCM(282, 662) = 93342

GCD(282, 662) = ( 282 x 662 ) / 93342

= 282 / 662

= 282

Step2:

LCM(2, 686) = 686

GCD(2, 686) = ( 2 x 686 ) / 686

= 2 / 686

= 2

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 282, 662, 686, 645 is 1
