Given numbers are 813,453,720,352

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

The LCM of 813,453,720,352 is 648188640.

Find LCM of 813,453,720,352 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 271 x 151 x 15 x 22 = 648188640

Therefore, the lowest common multiple of 813,453,720,352 is 648188640.

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.

813 x 453 x 720 x 352 = 93339164160

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.

813 : 1, 3, 271, 813

453 : 1, 3, 151, 453

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

352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,453,720,352, is 1.

Now, the common factors can be found like this.

813:3x 271

453:3x 151

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

352:2x 2x 2x 2x 2x 11

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 3 = 144

Therefore, the value for common factors is 144.

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 = 93339164160/(1x144)

LCM = 93339164160/144

LCM = 648188640

Thus, we can understand that the LCM of 813,453,720,352 is 648188640.
