Given numbers are 103,221,615,287

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

The LCM of 103,221,615,287 is 97994715.

Find LCM of 103,221,615,287 with Prime Factorization

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

41 x 103 x 221 x 15 x 7 = 97994715

Therefore, the lowest common multiple of 103,221,615,287 is 97994715.

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.

103 x 221 x 615 x 287 = 4017783315

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.

103 : 1, 103

221 : 1, 13, 17, 221

615 : 1, 3, 5, 15, 41, 123, 205, 615

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,221,615,287, is 1.

Now, the common factors can be found like this.

103:103

221:13x 17

615:3x 5x 41

287:7x 41

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

41 = 41

Therefore, the value for common factors is 41.

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 = 4017783315/(1x41)

LCM = 4017783315/41

LCM = 97994715

Thus, we can understand that the LCM of 103,221,615,287 is 97994715.

Here are some samples of LCM of two or more Numbers calculations.
