Steps to Calculate GCD of 661, 287, 307, 667 using LCM Formula
Given numbers are 661, 287, 307, 667
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 287) = 189707
GCD(661, 287) = ( 661 x 287 ) / 189707
= 661 / 287
= 661
Step2:
LCM(1, 307) = 307
GCD(1, 307) = ( 1 x 307 ) / 307
= 1 / 307
= 1
Step3:
LCM(1, 667) = 667
GCD(1, 667) = ( 1 x 667 ) / 667
= 1 / 667
= 1
So, Greatest Common Divisor of 661, 287, 307, 667 is 1
