Given numbers are 501,689,921,225

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

The LCM of 501,689,921,225 is 7947976725.

Find LCM of 501,689,921,225 with Prime Factorization

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

3 x 167 x 689 x 307 x 75 = 7947976725

Therefore, the lowest common multiple of 501,689,921,225 is 7947976725.

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.

501 x 689 x 921 x 225 = 71531790525

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.

501 : 1, 3, 167, 501

689 : 1, 13, 53, 689

921 : 1, 3, 307, 921

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 501,689,921,225, is 1.

Now, the common factors can be found like this.

501:3x 167

689:13x 53

921:3x 307

225:3x 3x 5x 5

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 71531790525/(1x9)

LCM = 71531790525/9

LCM = 7947976725

Thus, we can understand that the LCM of 501,689,921,225 is 7947976725.
