Given numbers are 457,399,154,664

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

The LCM of 457,399,154,664 is 1331833272.

Find LCM of 457,399,154,664 with Prime Factorization

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

2 x 7 x 457 x 57 x 11 x 332 = 1331833272

Therefore, the lowest common multiple of 457,399,154,664 is 1331833272.

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.

457 x 399 x 154 x 664 = 18645665808

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.

457 : 1, 457

399 : 1, 3, 7, 19, 21, 57, 133, 399

154 : 1, 2, 7, 11, 14, 22, 77, 154

664 : 1, 2, 4, 8, 83, 166, 332, 664

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,399,154,664, is 1.

Now, the common factors can be found like this.

457:457

399:3x 7x 19

154:2x 7x 11

664:2x 2x 2x 83

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 18645665808/(1x14)

LCM = 18645665808/14

LCM = 1331833272

Thus, we can understand that the LCM of 457,399,154,664 is 1331833272.
