Given numbers are 915,278,528,221

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

The LCM of 915,278,528,221 is 4946987760.

Find LCM of 915,278,528,221 with Prime Factorization

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

2 x 3 x 305 x 139 x 88 x 221 = 4946987760

Therefore, the lowest common multiple of 915,278,528,221 is 4946987760.

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.

915 x 278 x 528 x 221 = 29681926560

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.

915 : 1, 3, 5, 15, 61, 183, 305, 915

278 : 1, 2, 139, 278

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,278,528,221, is 1.

Now, the common factors can be found like this.

915:3x 5x 61

278:2x 139

528:2x 2x 2x 2x 3x 11

221:13x 17

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 29681926560/(1x6)

LCM = 29681926560/6

LCM = 4946987760

Thus, we can understand that the LCM of 915,278,528,221 is 4946987760.
