Given numbers are 987,638,375

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

The LCM of 987,638,375 is 78713250.

Find LCM of 987,638,375 with Prime Factorization

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

3 x 329 x 638 x 125 = 78713250

Therefore, the lowest common multiple of 987,638,375 is 78713250.

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.

987 x 638 x 375 = 236139750

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.

987 : 1, 3, 7, 21, 47, 141, 329, 987

638 : 1, 2, 11, 22, 29, 58, 319, 638

375 : 1, 3, 5, 15, 25, 75, 125, 375

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,638,375, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

638:2x 11x 29

375:3x 5x 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.

3 = 3

Therefore, the value for common factors is 3.

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 = 236139750/(1x3)

LCM = 236139750/3

LCM = 78713250

Thus, we can understand that the LCM of 987,638,375 is 78713250.
