GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 378) = 5670
GCD(810, 378) = ( 810 x 378 ) / 5670
= 810 / 378
= 810
Step2:
LCM(54, 416) = 11232
GCD(54, 416) = ( 54 x 416 ) / 11232
= 54 / 416
= 54
Step3:
LCM(2, 518) = 518
GCD(2, 518) = ( 2 x 518 ) / 518
= 2 / 518
= 2
So, Greatest Common Divisor of 810, 378, 416, 518 is 2
