Given numbers are 215,521,903,719

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

The LCM of 215,521,903,719 is 1691314485.

Find LCM of 215,521,903,719 with Prime Factorization

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

43 x 5 x 521 x 21 x 719 = 1691314485

Therefore, the lowest common multiple of 215,521,903,719 is 1691314485.

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.

215 x 521 x 903 x 719 = 72726522855

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.

215 : 1, 5, 43, 215

521 : 1, 521

903 : 1, 3, 7, 21, 43, 129, 301, 903

719 : 1, 719

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,521,903,719, is 1.

Now, the common factors can be found like this.

215:5x 43

521:521

903:3x 7x 43

719:719

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 = 72726522855/(1x43)

LCM = 72726522855/43

LCM = 1691314485

Thus, we can understand that the LCM of 215,521,903,719 is 1691314485.
