Given numbers are 615,988,224,257

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

The LCM of 615,988,224,257 is 8744867040.

Find LCM of 615,988,224,257 with Prime Factorization

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

2 x 2 x 615 x 247 x 56 x 257 = 8744867040

Therefore, the lowest common multiple of 615,988,224,257 is 8744867040.

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.

615 x 988 x 224 x 257 = 34979468160

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.

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

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,988,224,257, is 1.

Now, the common factors can be found like this.

615:3x 5x 41

988:2x 2x 13x 19

224:2x 2x 2x 2x 2x 7

257:257

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 34979468160/(1x4)

LCM = 34979468160/4

LCM = 8744867040

Thus, we can understand that the LCM of 615,988,224,257 is 8744867040.
