Given numbers are 660,361,357,165,815

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

The LCM of 660,361,357,165,815 is 4621529220.

Find LCM of 660,361,357,165,815 with Prime Factorization

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

3 x 5 x 11 x 4 x 361 x 119 x 1 x 163 = 4621529220

Therefore, the lowest common multiple of 660,361,357,165,815 is 4621529220.

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.

660 x 361 x 357 x 165 x 815 = 11438284819500

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.

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

361 : 1, 19, 361

357 : 1, 3, 7, 17, 21, 51, 119, 357

165 : 1, 3, 5, 11, 15, 33, 55, 165

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,361,357,165,815, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

361:19x 19

357:3x 7x 17

165:3x 5x 11

815:5x 163

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

3x 3x 5x 5x 11 = 2475

Therefore, the value for common factors is 2475.

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 = 11438284819500/(1x2475)

LCM = 11438284819500/2475

LCM = 4621529220

Thus, we can understand that the LCM of 660,361,357,165,815 is 4621529220.
