Method to find the LCM of two numbers a & b:
1- Find the GCF(Greatest Common Factor) of a & b.
2- Find the product of a & b.
3- Divide the product of a & b by the result obtained in step 1.
STEP 1:
Greatest common factor can be found by the method of prime factorization.
Prime factorization of 121 = 11 x 11
Prime factorization of 132 = 11 x 12
GCF(121, 132) = 11
STEP 2:
Product of 121 & 132 = 15972
STEP 3:
LCM(121, 132) = 15972/11 = 1452

What number does 3 7 12 go into?
84This question is asking for the Lowest Common Multiple (LCM) - also called the Least Common Denominator (LCD).Generally, you can find the LCM of 2 of the numbers, then find the LCM of that number with the third.Since 3 and 7 are both prime, their LCM is 3x7=21. To find the LCM of 21 and 12, make a list of their multiples until you find a number common to both lists:12: 12. 24, 36, 48, 60, 72, 84, ...21: 21, 42, 63, 84, ...

What is the LCM of 7 3 21?
To find the Least Common Multiple (LCM) of 7, 3, and 21, we first need to identify the prime factors of each number. The prime factors of 7 are 7, of 3 are 3, and of 21 are 3 and 7. Then, we take the highest power of each prime factor that appears in any of the numbers. In this case, the LCM of 7, 3, and 21 is 21, as it includes the highest power of both 7 and 3.
