Find LCM of 393,180,540,448 with Prime Factorization


2 393, 180, 540, 448
2 393, 90, 270, 224
3 393, 45, 135, 112
3 131, 15, 45, 112
5 131, 5, 15, 112
131, 1, 3, 112

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

2 x 2 x 3 x 3 x 5 x 131 x 1 x 3 x 112 = 7922880

Therefore, the lowest common multiple of 393,180,540,448 is 7922880.

LCM Formula to Find Lowest Common Multiple of 393,180,540,448

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.

393 x 180 x 540 x 448 = 17113420800

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.

393 : 1, 3, 131, 393

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,180,540,448, is 1.

Now, the common factors can be found like this.

393:3x 131

180:2x 2x 3x 3x 5

540:2x 2x 3x 3x 3x 5

448:2x 2x 2x 2x 2x 2x 7

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 3x 5 = 2160

Therefore, the value for common factors is 2160.

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 = 17113420800/(1x2160)

LCM = 17113420800/2160

LCM = 7922880

Thus, we can understand that the LCM of 393,180,540,448 is 7922880.
