Find LCM of 720,474,312,663 with Prime Factorization


2 720, 474, 312, 663
2 360, 237, 156, 663
2 180, 237, 78, 663
3 90, 237, 39, 663
13 30, 79, 13, 221
30, 79, 1, 17

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

2 x 2 x 2 x 3 x 13 x 30 x 79 x 1 x 17 = 12570480

Therefore, the lowest common multiple of 720,474,312,663 is 12570480.

LCM Formula to Find Lowest Common Multiple of 720,474,312,663

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.

720 x 474 x 312 x 663 = 70595815680

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

474 : 1, 2, 3, 6, 79, 158, 237, 474

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

663 : 1, 3, 13, 17, 39, 51, 221, 663

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,474,312,663, is 3.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

474:2x 3x 79

312:2x 2x 2x 3x 13

663:3x 13x 17

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 3x 3x 13 = 1872

Therefore, the value for common factors is 1872.

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 = 70595815680/(3x1872)

LCM = 70595815680/5616

LCM = 12570480

Thus, we can understand that the LCM of 720,474,312,663 is 12570480.
