Given numbers are 834, 556, 202, 840

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

Apply this formula for all numbers.

Step1:

LCM(834, 556) = 1668

GCD(834, 556) = ( 834 x 556 ) / 1668

= 834 / 556

= 834

Step2:

LCM(278, 202) = 28078

GCD(278, 202) = ( 278 x 202 ) / 28078

= 278 / 202

= 278

Step3:

LCM(2, 840) = 840

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

= 2 / 840

= 2

So, Greatest Common Divisor of 834, 556, 202, 840 is 2
