Given numbers are 665,154,352,454

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

The LCM of 665,154,352,454 is 53136160.

Find LCM of 665,154,352,454 with Prime Factorization

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

2 x 7 x 11 x 95 x 1 x 16 x 227 = 53136160

Therefore, the lowest common multiple of 665,154,352,454 is 53136160.

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.

665 x 154 x 352 x 454 = 16365937280

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

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

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

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,154,352,454, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

154:2x 7x 11

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

454:2x 227

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 7x 11 = 308

Therefore, the value for common factors is 308.

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 = 16365937280/(1x308)

LCM = 16365937280/308

LCM = 53136160

Thus, we can understand that the LCM of 665,154,352,454 is 53136160.
