Given numbers are 845,458,415,840

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

The LCM of 845,458,415,840 is 2698233720.

Find LCM of 845,458,415,840 with Prime Factorization

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

2 x 5 x 169 x 229 x 83 x 84 = 2698233720

Therefore, the lowest common multiple of 845,458,415,840 is 2698233720.

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.

845 x 458 x 415 x 840 = 134911686000

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.

845 : 1, 5, 13, 65, 169, 845

458 : 1, 2, 229, 458

415 : 1, 5, 83, 415

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,458,415,840, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

458:2x 229

415:5x 83

840:2x 2x 2x 3x 5x 7

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

2x 5x 5 = 50

Therefore, the value for common factors is 50.

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 = 134911686000/(1x50)

LCM = 134911686000/50

LCM = 2698233720

Thus, we can understand that the LCM of 845,458,415,840 is 2698233720.
