Final answer:
By factorizing the numbers 147 and 63, you can find their LCM by multiplying each factor the greatest number of times it occurs in any of the numbers. Therefore, the LCM of 147 and 63 is 441.
Explanation:
To find the Lowest Common Multiple (LCM) of 147 and 63 by factoring, you first need to factorize these two numbers. The prime factorization of 147 is 3 x 7 x 7 and of 63 is 3 x 3 x 7.
The LCM is found by multiplying each factor the greatest number of times it occurs in either number. In this case, you have 3 two times (from 63), and 7 two times (from 147). Therefore, the LCM is 3 x 3 x 7 x 7 which equals 441.
