Given numbers are 751,172,215,981

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

The LCM of 751,172,215,981 is 633588660.

Find LCM of 751,172,215,981 with Prime Factorization

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

43 x 751 x 4 x 5 x 981 = 633588660

Therefore, the lowest common multiple of 751,172,215,981 is 633588660.

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.

751 x 172 x 215 x 981 = 27244312380

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.

751 : 1, 751

172 : 1, 2, 4, 43, 86, 172

215 : 1, 5, 43, 215

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,172,215,981, is 1.

Now, the common factors can be found like this.

751:751

172:2x 2x 43

215:5x 43

981:3x 3x 109

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

43 = 43

Therefore, the value for common factors is 43.

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 = 27244312380/(1x43)

LCM = 27244312380/43

LCM = 633588660

Thus, we can understand that the LCM of 751,172,215,981 is 633588660.
