Given numbers are 469,115,638,470

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

The LCM of 469,115,638,470 is 1617294910.

Find LCM of 469,115,638,470 with Prime Factorization

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

2 x 5 x 469 x 23 x 319 x 47 = 1617294910

Therefore, the lowest common multiple of 469,115,638,470 is 1617294910.

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.

469 x 115 x 638 x 470 = 16172949100

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.

469 : 1, 7, 67, 469

115 : 1, 5, 23, 115

638 : 1, 2, 11, 22, 29, 58, 319, 638

470 : 1, 2, 5, 10, 47, 94, 235, 470

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 469,115,638,470, is 1.

Now, the common factors can be found like this.

469:7x 67

115:5x 23

638:2x 11x 29

470:2x 5x 47

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 16172949100/(1x10)

LCM = 16172949100/10

LCM = 1617294910

Thus, we can understand that the LCM of 469,115,638,470 is 1617294910.
