Steps to Calculate GCD of 189, 313, 158, 646 using LCM Formula
Given numbers are 189, 313, 158, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 313) = 59157
GCD(189, 313) = ( 189 x 313 ) / 59157
= 189 / 313
= 189
Step2:
LCM(1, 158) = 158
GCD(1, 158) = ( 1 x 158 ) / 158
= 1 / 158
= 1
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 189, 313, 158, 646 is 1
