Given numbers are 430,520,390,676,581

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

The LCM of 430,520,390,676,581 is 506655240.

Find LCM of 430,520,390,676,581 with Prime Factorization

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

2 x 2 x 5 x 13 x 43 x 2 x 3 x 13 x 581 = 506655240

Therefore, the lowest common multiple of 430,520,390,676,581 is 506655240.

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.

430 x 520 x 390 x 676 x 581 = 34249894224000

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.

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

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,520,390,676,581, is 1.

Now, the common factors can be found like this.

430:2x 5x 43

520:2x 2x 2x 5x 13

390:2x 3x 5x 13

676:2x 2x 13x 13

581:7x 83

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 2x 5x 5x 13x 13 = 67600

Therefore, the value for common factors is 67600.

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 = 34249894224000/(1x67600)

LCM = 34249894224000/67600

LCM = 506655240

Thus, we can understand that the LCM of 430,520,390,676,581 is 506655240.
