Given numbers are 7218,5128

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

The LCM of 7218,5128 is 18506952.

Find LCM of 7218,5128 with Prime Factorization

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

2 x 3609 x 2564 = 18506952

Therefore, the lowest common multiple of 7218,5128 is 18506952.

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.

7218 x 5128 = 37013904

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.

7218 : 1, 2, 3, 6, 9, 18, 401, 802, 1203, 2406, 3609, 7218

5128 : 1, 2, 4, 8, 641, 1282, 2564, 5128

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7218,5128, is 2.

Now, the common factors can be found like this.

7218:2x 3x 3x 401

5128:2x 2x 2x 641

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 = 37013904/(2x1)

LCM = 37013904/2

LCM = 18506952

Thus, we can understand that the LCM of 7218,5128 is 18506952.

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

• LCM of 6552, 8983
