What is the LCM of 120 and 16?
To find the LCM, you need to find the GCF. 120 factors to [2 2 2 3 5] 16 factors to [2 2 2 2] Common factors [2 2 2] GCF = 8 Now, the LCM is the product divided by the GCF 120 * 16 / 8 = 240 ■
Could you use the prime factorization to determine LCM and GCF of 10 and 6?
2 x 3 = 6 2 x 5 = 10 The GCF is 2.
How do you use the ladder meathod to find the GCF and the LCM of a number?
You don't find the GCF and LCM of a single number, you need at least two. Ladders, trees, fireworks, rainbows... It's all the same thing, just different ways of writing the factors on the page. Find a way that works for you. To find the GCF and LCM of 30 and 42, you need to factor them. 30 42 15,2 21,2 5,3,2 7,3,2 2 x 3 x 5 = 30 and 2 x 3 x 7 = 42 To find the GCF, select the common factors. 2 x 3 = 6, the GCF. To find the LCM, combine the factors, eliminating duplicates. 2 x 3 x 5 x 7 = 210, the LCM
What is the GCF and LCM of 105 and 75?
