Given numbers are 453,720,391,890

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

The LCM of 453,720,391,890 is 3783347280.

Find LCM of 453,720,391,890 with Prime Factorization

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

2 x 3 x 5 x 151 x 24 x 391 x 89 = 3783347280

Therefore, the lowest common multiple of 453,720,391,890 is 3783347280.

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.

453 x 720 x 391 x 890 = 113500418400

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.

453 : 1, 3, 151, 453

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

391 : 1, 17, 23, 391

890 : 1, 2, 5, 10, 89, 178, 445, 890

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,720,391,890, is 1.

Now, the common factors can be found like this.

453:3x 151

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

391:17x 23

890:2x 5x 89

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

2x 3x 5 = 30

Therefore, the value for common factors is 30.

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 = 113500418400/(1x30)

LCM = 113500418400/30

LCM = 3783347280

Thus, we can understand that the LCM of 453,720,391,890 is 3783347280.
