How do you find the LCM for 75 and 105?
One way is to write out each in their prime factorization: 75 = 3x5x5 105 = 3x5x7 Write each so that common terms are directly above/below each other: 3 5 5 3 5 7 Then multiply the number in each column once: 3x5x5x7 (because there is one column of threes, two columns of fives, and one column of sevens). Hence, the LCM of 75 and 105 is 525.
