Given numbers are 4,781,530,387

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

The LCM of 4,781,530,387 is 320381820.

Find LCM of 4,781,530,387 with Prime Factorization

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

2 x 2 x 781 x 265 x 387 = 320381820

Therefore, the lowest common multiple of 4,781,530,387 is 320381820.

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.

4 x 781 x 530 x 387 = 640763640

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.

4 : 1, 2, 4

781 : 1, 11, 71, 781

530 : 1, 2, 5, 10, 53, 106, 265, 530

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4,781,530,387, is 1.

Now, the common factors can be found like this.

4:2x 2

781:11x 71

530:2x 5x 53

387:3x 3x 43

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 = 640763640/(1x2)

LCM = 640763640/2

LCM = 320381820

Thus, we can understand that the LCM of 4,781,530,387 is 320381820.

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

• LCM of 6, 472, 116, 899
