Given numbers are 846, 810, 342, 621

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

Apply this formula for all numbers.

Step1:

LCM(846, 810) = 38070

GCD(846, 810) = ( 846 x 810 ) / 38070

= 846 / 810

= 846

Step2:

LCM(18, 342) = 342

GCD(18, 342) = ( 18 x 342 ) / 342

= 18 / 342

= 18

Step3:

LCM(18, 621) = 1242

GCD(18, 621) = ( 18 x 621 ) / 1242

= 18 / 621

= 18

So, Greatest Common Divisor of 846, 810, 342, 621 is 9
