Lowest common multiple LCM by prime factorization Tiger Algebra not only finds the lcm 15 21 but its clear step by step explanation of the solution helps to better understand and remember the method Calculate LCM of 15 and 21 is 105 Least common multiple can be found by multiplying the highest exponent prime factors of 15 and 21 First we will calculate the prime factors of 15 and 21 Prime Factorization of 15 Prime factors of 15 are 3 5 Prime factorization of 15 in exponential form is 15 3 1 5 1 Prime Factorization of 21
To calculate the LCM of two or more numbers factorize each number into prime factors write into the exponents form multiply the factors with the highest powers to get the LCM What LCM used for LCM least common multiple is the smallest number divisible by both numbers it is used to find the lowest common denominator of two or more fractions Prime Factorization of 21 is as follows Prime factors of 21 are 3 7 Prime factorization of 21 in exponent form is 21 3 1 7 1 Step 2 Multiply together each of the Prime Numbers with the highest power to obtain the Least Common Multiple On doing so you will get the resultant equation as 3 1 5 1 7 1 105
