Given numbers are 816, 636, 432, 208

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

Apply this formula for all numbers.

Step1:

LCM(816, 636) = 43248

GCD(816, 636) = ( 816 x 636 ) / 43248

= 816 / 636

= 816

Step2:

LCM(12, 432) = 432

GCD(12, 432) = ( 12 x 432 ) / 432

= 12 / 432

= 12

Step3:

LCM(12, 208) = 624

GCD(12, 208) = ( 12 x 208 ) / 624

= 12 / 208

= 12

So, Greatest Common Divisor of 816, 636, 432, 208 is 4
