Given numbers are 138,840,533,478

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

The LCM of 138,840,533,478 is 2461116840.

Find LCM of 138,840,533,478 with Prime Factorization

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

2 x 3 x 23 x 140 x 533 x 239 = 2461116840

Therefore, the lowest common multiple of 138,840,533,478 is 2461116840.

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.

138 x 840 x 533 x 478 = 29533402080

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

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

533 : 1, 13, 41, 533

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,840,533,478, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

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

533:13x 41

478:2x 239

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 3 = 12

Therefore, the value for common factors is 12.

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 = 29533402080/(1x12)

LCM = 29533402080/12

LCM = 2461116840

Thus, we can understand that the LCM of 138,840,533,478 is 2461116840.
