Given numbers are 4218,9021

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 4218,9021 is 12683526.

Find LCM of 4218,9021 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 1406 x 3007 = 12683526

Therefore, the lowest common multiple of 4218,9021 is 12683526.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

4218 x 9021 = 38050578

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

4218 : 1, 2, 3, 6, 19, 37, 38, 57, 74, 111, 114, 222, 703, 1406, 2109, 4218

9021 : 1, 3, 31, 93, 97, 291, 3007, 9021

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4218,9021, is 3.

Now, the common factors can be found like this.

4218:2x 3x 19x 37

9021:3x 31x 97

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

= 1

Therefore, the value for common factors is 1.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 38050578/(3x1)

LCM = 38050578/3

LCM = 12683526

Thus, we can understand that the LCM of 4218,9021 is 12683526.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 9455, 7521
