Given numbers are 819, 645, 167, 212

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

Apply this formula for all numbers.

Step1:

LCM(819, 645) = 176085

GCD(819, 645) = ( 819 x 645 ) / 176085

= 819 / 645

= 819

Step2:

LCM(3, 167) = 501

GCD(3, 167) = ( 3 x 167 ) / 501

= 3 / 167

= 3

Step3:

LCM(1, 212) = 212

GCD(1, 212) = ( 1 x 212 ) / 212

= 1 / 212

= 1

So, Greatest Common Divisor of 819, 645, 167, 212 is 1
