Steps to Calculate GCD of 921, 178, 515, 563 using LCM Formula
Given numbers are 921, 178, 515, 563
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 178) = 163938
GCD(921, 178) = ( 921 x 178 ) / 163938
= 921 / 178
= 921
Step2:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
Step3:
LCM(1, 563) = 563
GCD(1, 563) = ( 1 x 563 ) / 563
= 1 / 563
= 1
So, Greatest Common Divisor of 921, 178, 515, 563 is 1
