GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 912) = 196080
GCD(645, 912) = ( 645 x 912 ) / 196080
= 645 / 912
= 645
Step2:
LCM(3, 771) = 771
GCD(3, 771) = ( 3 x 771 ) / 771
= 3 / 771
= 3
Step3:
LCM(3, 282) = 282
GCD(3, 282) = ( 3 x 282 ) / 282
= 3 / 282
= 3
So, Greatest Common Divisor of 645, 912, 771, 282 is 3
