### Finding both the GCF and LCM (Example Problem)

Check out Bas Rutten's Liver Shot on MMA Surge: http://bit.ly/MMASurgeEp1 Mahalo math expert Allison Moffett shows you how to find the GFC and LCM using prime factorizations.? GCF --------------------------------------------------------------------- The greatest common factor, or GCF, is the greatest number that divides exactly into two or more numbers.This example shows the greatest factors that two numbers (a, b) have in common. When choosing between numbers with same base number and exponents, take the lower power because the larger one will have the smaller power in common.The integers at the end are not common, because they do not have any factors in common when you try to divide them evenly. LCM --------------------------------------------------------------------- To find the least common multiple, or LCM, take the largest power that appears in either prime factorization.This example shows the least common multiples of numbers (a, b). When using prime factorization with common base numbers, choose the multiple with the higher power. Read more by visiting our page at: http://www.mahalo.com/finding-the-gcf-and-lcm/
