Given numbers are 798, 654, 290, 840

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

Apply this formula for all numbers.

Step1:

LCM(798, 654) = 86982

GCD(798, 654) = ( 798 x 654 ) / 86982

= 798 / 654

= 798

Step2:

LCM(6, 290) = 870

GCD(6, 290) = ( 6 x 290 ) / 870

= 6 / 290

= 6

Step3:

LCM(2, 840) = 840

GCD(2, 840) = ( 2 x 840 ) / 840

= 2 / 840

= 2

So, Greatest Common Divisor of 798, 654, 290, 840 is 2
