Given numbers are 378, 216, 122, 636

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

Apply this formula for all numbers.

Step1:

LCM(378, 216) = 1512

GCD(378, 216) = ( 378 x 216 ) / 1512

= 378 / 216

= 378

Step2:

LCM(54, 122) = 3294

GCD(54, 122) = ( 54 x 122 ) / 3294

= 54 / 122

= 54

Step3:

LCM(2, 636) = 636

GCD(2, 636) = ( 2 x 636 ) / 636

= 2 / 636

= 2

So, Greatest Common Divisor of 378, 216, 122, 636 is 2
