Given numbers are 845,515,427,660

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

The LCM of 845,515,427,660 is 4905640740.

Find LCM of 845,515,427,660 with Prime Factorization

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

5 x 169 x 103 x 427 x 132 = 4905640740

Therefore, the lowest common multiple of 845,515,427,660 is 4905640740.

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 515 x 427 x 660 = 122641018500

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

515 : 1, 5, 103, 515

427 : 1, 7, 61, 427

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,515,427,660, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

515:5x 103

427:7x 61

660:2x 2x 3x 5x 11

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 122641018500/(1x25)

LCM = 122641018500/25

LCM = 4905640740

Thus, we can understand that the LCM of 845,515,427,660 is 4905640740.
