Steps to Calculate GCD of 387, 771, 303, 815 using LCM Formula
Given numbers are 387, 771, 303, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 771) = 99459
GCD(387, 771) = ( 387 x 771 ) / 99459
= 387 / 771
= 387
Step2:
LCM(3, 303) = 303
GCD(3, 303) = ( 3 x 303 ) / 303
= 3 / 303
= 3
Step3:
LCM(3, 815) = 2445
GCD(3, 815) = ( 3 x 815 ) / 2445
= 3 / 815
= 3
So, Greatest Common Divisor of 387, 771, 303, 815 is 1
