Given numbers are 416,645,403

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

The LCM of 416,645,403 is 8317920.

Find LCM of 416,645,403 with Prime Factorization

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

13 x 32 x 645 x 31 = 8317920

Therefore, the lowest common multiple of 416,645,403 is 8317920.

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.

416 x 645 x 403 = 108132960

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.

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

645 : 1, 3, 5, 15, 43, 129, 215, 645

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,645,403, is 1.

Now, the common factors can be found like this.

416:2x 2x 2x 2x 2x 13

645:3x 5x 43

403:13x 31

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

13 = 13

Therefore, the value for common factors is 13.

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 = 108132960/(1x13)

LCM = 108132960/13

LCM = 8317920

Thus, we can understand that the LCM of 416,645,403 is 8317920.
