Given numbers are 478,170,404,775

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

The LCM of 478,170,404,775 is 1272125300.

Find LCM of 478,170,404,775 with Prime Factorization

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

2 x 5 x 239 x 17 x 202 x 155 = 1272125300

Therefore, the lowest common multiple of 478,170,404,775 is 1272125300.

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.

478 x 170 x 404 x 775 = 25442506000

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.

478 : 1, 2, 239, 478

170 : 1, 2, 5, 10, 17, 34, 85, 170

404 : 1, 2, 4, 101, 202, 404

775 : 1, 5, 25, 31, 155, 775

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,170,404,775, is 1.

Now, the common factors can be found like this.

478:2x 239

170:2x 5x 17

404:2x 2x 101

775:5x 5x 31

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 5 = 20

Therefore, the value for common factors is 20.

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 = 25442506000/(1x20)

LCM = 25442506000/20

LCM = 1272125300

Thus, we can understand that the LCM of 478,170,404,775 is 1272125300.
