Given numbers are 989,203,215,431

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

The LCM of 989,203,215,431 is 432652885.

Find LCM of 989,203,215,431 with Prime Factorization

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

43 x 23 x 203 x 5 x 431 = 432652885

Therefore, the lowest common multiple of 989,203,215,431 is 432652885.

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.

989 x 203 x 215 x 431 = 18604074055

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.

989 : 1, 23, 43, 989

203 : 1, 7, 29, 203

215 : 1, 5, 43, 215

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,203,215,431, is 1.

Now, the common factors can be found like this.

989:23x 43

203:7x 29

215:5x 43

431:431

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 = 18604074055/(1x43)

LCM = 18604074055/43

LCM = 432652885

Thus, we can understand that the LCM of 989,203,215,431 is 432652885.
