Given numbers are 399,689,430,470

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

The LCM of 399,689,430,470 is 5555951310.

Find LCM of 399,689,430,470 with Prime Factorization

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

2 x 5 x 399 x 689 x 43 x 47 = 5555951310

Therefore, the lowest common multiple of 399,689,430,470 is 5555951310.

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.

399 x 689 x 430 x 470 = 55559513100

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.

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

689 : 1, 13, 53, 689

430 : 1, 2, 5, 10, 43, 86, 215, 430

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 399,689,430,470, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

689:13x 53

430:2x 5x 43

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 = 55559513100/(1x10)

LCM = 55559513100/10

LCM = 5555951310

Thus, we can understand that the LCM of 399,689,430,470 is 5555951310.
