Given numbers are 859,438,354,840

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

The LCM of 859,438,354,840 is 3107758920.

Find LCM of 859,438,354,840 with Prime Factorization

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

2 x 3 x 859 x 73 x 59 x 140 = 3107758920

Therefore, the lowest common multiple of 859,438,354,840 is 3107758920.

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.

859 x 438 x 354 x 840 = 111879321120

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.

859 : 1, 859

438 : 1, 2, 3, 6, 73, 146, 219, 438

354 : 1, 2, 3, 6, 59, 118, 177, 354

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 859,438,354,840, is 1.

Now, the common factors can be found like this.

859:859

438:2x 3x 73

354:2x 3x 59

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 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 111879321120/(1x36)

LCM = 111879321120/36

LCM = 3107758920

Thus, we can understand that the LCM of 859,438,354,840 is 3107758920.
