Given numbers are 398,503,710,787

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

The LCM of 398,503,710,787 is 55931200690.

Find LCM of 398,503,710,787 with Prime Factorization

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

2 x 199 x 503 x 355 x 787 = 55931200690

Therefore, the lowest common multiple of 398,503,710,787 is 55931200690.

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.

398 x 503 x 710 x 787 = 111862401380

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.

398 : 1, 2, 199, 398

503 : 1, 503

710 : 1, 2, 5, 10, 71, 142, 355, 710

787 : 1, 787

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,503,710,787, is 1.

Now, the common factors can be found like this.

398:2x 199

503:503

710:2x 5x 71

787:787

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

2 = 2

Therefore, the value for common factors is 2.

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 = 111862401380/(1x2)

LCM = 111862401380/2

LCM = 55931200690

Thus, we can understand that the LCM of 398,503,710,787 is 55931200690.

Here are some samples of LCM of two or more Numbers calculations.
