Given numbers are 810, 606, 40, 378

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

Apply this formula for all numbers.

Step1:

LCM(810, 606) = 81810

GCD(810, 606) = ( 810 x 606 ) / 81810

= 810 / 606

= 810

Step2:

LCM(6, 40) = 120

GCD(6, 40) = ( 6 x 40 ) / 120

= 6 / 40

= 6

Step3:

LCM(2, 378) = 378

GCD(2, 378) = ( 2 x 378 ) / 378

= 2 / 378

= 2

So, Greatest Common Divisor of 810, 606, 40, 378 is 2
