Calculate the LCM of 387,508,315,639

Given numbers are 387,508,315,639

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

The LCM of 387,508,315,639 is 488541060.

Find LCM of 387,508,315,639 with Prime Factorization


3 387, 508, 315, 639
3 129, 508, 105, 213
43, 508, 35, 71

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

3 x 3 x 43 x 508 x 35 x 71 = 488541060

Therefore, the lowest common multiple of 387,508,315,639 is 488541060.

LCM Formula to Find Lowest Common Multiple of 387,508,315,639

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.

387 x 508 x 315 x 639 = 39571825860

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.

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

508 : 1, 2, 4, 127, 254, 508

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,508,315,639, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

508:2x 2x 127

315:3x 3x 5x 7

639:3x 3x 71

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

3x 3x 3x 3 = 81

Therefore, the value for common factors is 81.

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 = 39571825860/(1x81)

LCM = 39571825860/81

LCM = 488541060

Thus, we can understand that the LCM of 387,508,315,639 is 488541060.
