Given numbers are 343,730,645,715

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

The LCM of 343,730,645,715 is 4618944330.

Find LCM of 343,730,645,715 with Prime Factorization

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

5 x 343 x 146 x 129 x 143 = 4618944330

Therefore, the lowest common multiple of 343,730,645,715 is 4618944330.

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.

343 x 730 x 645 x 715 = 115473608250

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.

343 : 1, 7, 49, 343

730 : 1, 2, 5, 10, 73, 146, 365, 730

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

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,730,645,715, is 1.

Now, the common factors can be found like this.

343:7x 7x 7

730:2x 5x 73

645:3x 5x 43

715:5x 11x 13

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 115473608250/(1x25)

LCM = 115473608250/25

LCM = 4618944330

Thus, we can understand that the LCM of 343,730,645,715 is 4618944330.
