Given numbers are 452,115,391,989

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

The LCM of 452,115,391,989 is 37997380.

Find LCM of 452,115,391,989 with Prime Factorization

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

23 x 452 x 5 x 17 x 43 = 37997380

Therefore, the lowest common multiple of 452,115,391,989 is 37997380.

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.

452 x 115 x 391 x 989 = 20100614020

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.

452 : 1, 2, 4, 113, 226, 452

115 : 1, 5, 23, 115

391 : 1, 17, 23, 391

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 452,115,391,989, is 1.

Now, the common factors can be found like this.

452:2x 2x 113

115:5x 23

391:17x 23

989:23x 43

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

23x 23 = 529

Therefore, the value for common factors is 529.

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 = 20100614020/(1x529)

LCM = 20100614020/529

LCM = 37997380

Thus, we can understand that the LCM of 452,115,391,989 is 37997380.
