Steps to Calculate GCD of 946, 187, 815, 646 using LCM Formula
Given numbers are 946, 187, 815, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(946, 187) = 16082
GCD(946, 187) = ( 946 x 187 ) / 16082
= 946 / 187
= 946
Step2:
LCM(11, 815) = 8965
GCD(11, 815) = ( 11 x 815 ) / 8965
= 11 / 815
= 11
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 946, 187, 815, 646 is 1
