Steps to Calculate GCD of 915, 643, 209, 606 using LCM Formula
Given numbers are 915, 643, 209, 606
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(915, 643) = 588345
GCD(915, 643) = ( 915 x 643 ) / 588345
= 915 / 643
= 915
Step2:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
Step3:
LCM(1, 606) = 606
GCD(1, 606) = ( 1 x 606 ) / 606
= 1 / 606
= 1
So, Greatest Common Divisor of 915, 643, 209, 606 is 1
