Given numbers are 451,938,989,161

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

The LCM of 451,938,989,161 is 418384582.

Find LCM of 451,938,989,161 with Prime Factorization

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

7 x 23 x 451 x 134 x 43 x 1 = 418384582

Therefore, the lowest common multiple of 451,938,989,161 is 418384582.

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.

451 x 938 x 989 x 161 = 67359917702

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.

451 : 1, 11, 41, 451

938 : 1, 2, 7, 14, 67, 134, 469, 938

989 : 1, 23, 43, 989

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,938,989,161, is 1.

Now, the common factors can be found like this.

451:11x 41

938:2x 7x 67

989:23x 43

161:7x 23

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 67359917702/(1x161)

LCM = 67359917702/161

LCM = 418384582

Thus, we can understand that the LCM of 451,938,989,161 is 418384582.
