Given numbers are 346,431,720,718,290

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

The LCM of 346,431,720,718,290 is 558918282960.

Find LCM of 346,431,720,718,290 with Prime Factorization

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

2 x 5 x 173 x 431 x 72 x 359 x 29 = 558918282960

Therefore, the lowest common multiple of 346,431,720,718,290 is 558918282960.

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.

346 x 431 x 720 x 718 x 290 = 22356731318400

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.

346 : 1, 2, 173, 346

431 : 1, 431

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

718 : 1, 2, 359, 718

290 : 1, 2, 5, 10, 29, 58, 145, 290

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 346,431,720,718,290, is 1.

Now, the common factors can be found like this.

346:2x 173

431:431

720:2x 2x 2x 2x 3x 3x 5

718:2x 359

290:2x 5x 29

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 2x 5 = 40

Therefore, the value for common factors is 40.

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 = 22356731318400/(1x40)

LCM = 22356731318400/40

LCM = 558918282960

Thus, we can understand that the LCM of 346,431,720,718,290 is 558918282960.
