Given numbers are 840, 168, 78, 946

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

Apply this formula for all numbers.

Step1:

LCM(840, 168) = 840

GCD(840, 168) = ( 840 x 168 ) / 840

= 840 / 168

= 840

Step2:

LCM(168, 78) = 2184

GCD(168, 78) = ( 168 x 78 ) / 2184

= 168 / 78

= 168

Step3:

LCM(6, 946) = 2838

GCD(6, 946) = ( 6 x 946 ) / 2838

= 6 / 946

= 6

So, Greatest Common Divisor of 840, 168, 78, 946 is 2
