GCF(8,18) = 2 LCM(8,18) = ( 8 × 18) / 2 LCM(8,18) = 144 / 2 LCM(8,18) = 72. Least Common Multiple (LCM) of 8 and 18 with Primes. Least common multiple can be found by multiplying the highest exponent prime factors of 8 and 18. First we will calculate the ...The gcf of 18 and 27 is the largest positive integer that divides the numbers 18 and 27 without a remainder. Spelled out, it is the greatest common factor of 18 and 27. Here you can find the result for 18 and 27, along with a total of three methods for computing it.We need to calculate greatest common factor 51 and 18, than apply into the LCM equation. GCF(51,18) = 3 LCM(51,18) = ( 51 × 18) / 3 LCM(51,18) = 918 / 3 LCM(51,18) = 306. Least Common Multiple (LCM) of 51 and 18 with Primes. Least common multiple can be found by multiplying the highest exponent prime factors of 51 and 18.The factors of 27 (all the whole numbers that can divide the number without a remainder) are 1, 3, 9 and 27; The factors of 18 are 1, 2, 3, 6, 9 and 18. The second step is to analyze which are the common divisors. It is not difficult to see that the 'Greatest Common Factor' or 'Divisor' for 27 and 18 is 9. The GCF is the largest common positive ...Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 …. 6, 12, and 18 are common multiples of 2 and 3. The number 6 is the smallest. Therefore, 6 is the least common multiple of 2 and 3. So, what is LCM in math? The LCM of two numbers is the smallest number divisible by both numbers.The number 27 is a composite number. Now let us find the prime factors of 27. The first step is to divide the number 27 with the smallest prime number, i.e. 2. 27 ÷ 2 = 13.5. But, factors cannot be a fraction, therefore, 2 is not the prime factor for 27. Now, proceed to the next prime numbers, i.e. 3, 5, 7 and so on.To find the Least Common Multiple or LCM of 32, decompose all numbers into prime factors and choose the common and uncommon prime factors with the greatest exponent.
