The least common multiple, or LCM, is another number that's useful in solving many math problems. Let's find the LCM of 30 and 45. One way to find the least common multiple of two numbers is to first list the prime factors of each number.
30 = 2 × 3 × 5
45 = 3 × 3 × 5
Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
2: one occurrence
3: two occurrences
5: one occurrence
2 × 3 × 3 × 5 = 90 <— LCM
After you've calculated a least common multiple, always check to be sure your answer can be divided evenly by both numbers.
Answer:
Noor's age is 12 & Salma's age is 18
Step-by-step explanation:
Noor's age: N
Salma's age: S
: given
: given
: isolate "N"
: substitute the value of N for N to find the value of "S"
: subtract 3 from both sides
≡ 
: multiply both sides by 2
: add like values
: divide both sides by 3
S = 18
now insert that value into the initial equation:
: subtract 18 from both sides
