Given numbers are 812, 678, 454, 800
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 678) = 275268
GCD(812, 678) = ( 812 x 678 ) / 275268
= 812 / 678
= 812
Step2:
LCM(2, 454) = 454
GCD(2, 454) = ( 2 x 454 ) / 454
= 2 / 454
= 2
Step3:
LCM(2, 800) = 800
GCD(2, 800) = ( 2 x 800 ) / 800
= 2 / 800
= 2
So, Greatest Common Divisor of 812, 678, 454, 800 is 2
