The LCM of 391,943,828,753 is 144856116.

Find LCM of 391,943,828,753 with Prime Factorization


3 391, 943, 828, 753
23 391, 943, 276, 251
17, 41, 12, 251

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

3 x 23 x 17 x 41 x 12 x 251 = 144856116

Therefore, the lowest common multiple of 391,943,828,753 is 144856116.

LCM Formula to Find Lowest Common Multiple of 391,943,828,753

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.

391 x 943 x 828 x 753 = 229886656092

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.

391 : 1, 17, 23, 391

943 : 1, 23, 41, 943

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

753 : 1, 3, 251, 753

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,943,828,753, is 1.

Now, the common factors can be found like this.

391:17x 23

943:23x 41

828:2x 2x 3x 3x 23

753:3x 251

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

3x 23x 23 = 1587

Therefore, the value for common factors is 1587.

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 = 229886656092/(1x1587)

LCM = 229886656092/1587

LCM = 144856116

Thus, we can understand that the LCM of 391,943,828,753 is 144856116.
