GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 168) = 21672
GCD(387, 168) = ( 387 x 168 ) / 21672
= 387 / 168
= 387
Step2:
LCM(3, 813) = 813
GCD(3, 813) = ( 3 x 813 ) / 813
= 3 / 813
= 3
Step3:
LCM(3, 672) = 672
GCD(3, 672) = ( 3 x 672 ) / 672
= 3 / 672
= 3
So, Greatest Common Divisor of 387, 168, 813, 672 is 3
