WebTo find the LCM of 18, 30 using GCF method find the GCF(18,30). We know the GCF of 18, 30 is 6 the largest number shared by all the factors. Now, use the formula to find LCM using GCF i.e. LCM(a,b) = ( a × b) / GCF(a,b) Substitute the given input values in place of a & b and the equation becomes. Web9 apr. 2015 · So, gcd ( a, b) = gcd ( a, − b). Obviously, the set of the common multiples of a and b is equal to the set of the common multiples of a and − b. So, lcm ( a, b) = lcm ( a, − b). So, gcd ( a, b) ⋅ lcm ( a, b) = a ⋅ b . If a < 0 and b > 0, then, by symmetry, gcd ( a, b) ⋅ lcm ( a, b) = a ⋅ b .
WebLeast Common Multiple (LCM) As with the greatest common divisor, we determine the multiples of the two numbers and then compare the common multiples and take the smallest of them, which will be the least common multiple (lcm).
