Given numbers are 1545,4638

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

The LCM of 1545,4638 is 2388570.

Find LCM of 1545,4638 with Prime Factorization

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

3 x 515 x 1546 = 2388570

Therefore, the lowest common multiple of 1545,4638 is 2388570.

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.

1545 x 4638 = 7165710

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.

1545 : 1, 3, 5, 15, 103, 309, 515, 1545

4638 : 1, 2, 3, 6, 773, 1546, 2319, 4638

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1545,4638, is 3.

Now, the common factors can be found like this.

1545:3x 5x 103

4638:2x 3x 773

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 = 7165710/(3x1)

LCM = 7165710/3

LCM = 2388570

Thus, we can understand that the LCM of 1545,4638 is 2388570.

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

• LCM of 5091, 2723
