Given numbers are 785,391,815

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

The LCM of 785,391,815 is 50030405.

Find LCM of 785,391,815 with Prime Factorization

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

5 x 157 x 391 x 163 = 50030405

Therefore, the lowest common multiple of 785,391,815 is 50030405.

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.

785 x 391 x 815 = 250152025

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.

785 : 1, 5, 157, 785

391 : 1, 17, 23, 391

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,391,815, is 1.

Now, the common factors can be found like this.

785:5x 157

391:17x 23

815:5x 163

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

5 = 5

Therefore, the value for common factors is 5.

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 = 250152025/(1x5)

LCM = 250152025/5

LCM = 50030405

Thus, we can understand that the LCM of 785,391,815 is 50030405.

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

• LCM of 956, 101, 588
• LCM of 770, 289, 718
