Find LCM of 144,506,490,920 with Prime Factorization


2 144, 506, 490, 920
2 72, 253, 245, 460
2 36, 253, 245, 230
5 18, 253, 245, 115
23 18, 253, 49, 23
18, 11, 49, 1

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

2 x 2 x 2 x 5 x 23 x 18 x 11 x 49 x 1 = 8925840

Therefore, the lowest common multiple of 144,506,490,920 is 8925840.

LCM Formula to Find Lowest Common Multiple of 144,506,490,920

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.

144 x 506 x 490 x 920 = 32847091200

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.

144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144

506 : 1, 2, 11, 22, 23, 46, 253, 506

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,506,490,920, is 2.

Now, the common factors can be found like this.

144:2x 2x 2x 2x 3x 3

506:2x 11x 23

490:2x 5x 7x 7

920:2x 2x 2x 5x 23

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

2x 2x 2x 2x 5x 23 = 1840

Therefore, the value for common factors is 1840.

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 = 32847091200/(2x1840)

LCM = 32847091200/3680

LCM = 8925840

Thus, we can understand that the LCM of 144,506,490,920 is 8925840.
