Given numbers are 213,494,453,840

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

The LCM of 213,494,453,840 is 2224393080.

Find LCM of 213,494,453,840 with Prime Factorization

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

2 x 3 x 71 x 247 x 151 x 140 = 2224393080

Therefore, the lowest common multiple of 213,494,453,840 is 2224393080.

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.

213 x 494 x 453 x 840 = 40039075440

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.

213 : 1, 3, 71, 213

494 : 1, 2, 13, 19, 26, 38, 247, 494

453 : 1, 3, 151, 453

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 213,494,453,840, is 1.

Now, the common factors can be found like this.

213:3x 71

494:2x 13x 19

453:3x 151

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 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 40039075440/(1x18)

LCM = 40039075440/18

LCM = 2224393080

Thus, we can understand that the LCM of 213,494,453,840 is 2224393080.
