Given numbers are 669,478,368,900

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

The LCM of 669,478,368,900 is 4412991600.

Find LCM of 669,478,368,900 with Prime Factorization

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

2 x 2 x 3 x 223 x 239 x 92 x 75 = 4412991600

Therefore, the lowest common multiple of 669,478,368,900 is 4412991600.

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.

669 x 478 x 368 x 900 = 105911798400

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.

669 : 1, 3, 223, 669

478 : 1, 2, 239, 478

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,478,368,900, is 1.

Now, the common factors can be found like this.

669:3x 223

478:2x 239

368:2x 2x 2x 2x 23

900:2x 2x 3x 3x 5x 5

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 3 = 24

Therefore, the value for common factors is 24.

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 = 105911798400/(1x24)

LCM = 105911798400/24

LCM = 4412991600

Thus, we can understand that the LCM of 669,478,368,900 is 4412991600.
