Steps to Calculate GCD of 771, 417, 551, 405 using LCM Formula
Given numbers are 771, 417, 551, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 417) = 107169
GCD(771, 417) = ( 771 x 417 ) / 107169
= 771 / 417
= 771
Step2:
LCM(3, 551) = 1653
GCD(3, 551) = ( 3 x 551 ) / 1653
= 3 / 551
= 3
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 771, 417, 551, 405 is 1
