Given numbers are 861,254,595,454

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

The LCM of 861,254,595,454 is 4219700730.

Find LCM of 861,254,595,454 with Prime Factorization

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

2 x 7 x 123 x 127 x 85 x 227 = 4219700730

Therefore, the lowest common multiple of 861,254,595,454 is 4219700730.

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.

861 x 254 x 595 x 454 = 59075810220

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

254 : 1, 2, 127, 254

595 : 1, 5, 7, 17, 35, 85, 119, 595

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,254,595,454, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

254:2x 127

595:5x 7x 17

454:2x 227

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 59075810220/(1x14)

LCM = 59075810220/14

LCM = 4219700730

Thus, we can understand that the LCM of 861,254,595,454 is 4219700730.
