Given numbers are 391,615,782,463

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

The LCM of 391,615,782,463 is 222670590.

Find LCM of 391,615,782,463 with Prime Factorization

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

17 x 23 x 1 x 615 x 2 x 463 = 222670590

Therefore, the lowest common multiple of 391,615,782,463 is 222670590.

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.

391 x 615 x 782 x 463 = 87064200690

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.

391 : 1, 17, 23, 391

615 : 1, 3, 5, 15, 41, 123, 205, 615

782 : 1, 2, 17, 23, 34, 46, 391, 782

463 : 1, 463

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,615,782,463, is 1.

Now, the common factors can be found like this.

391:17x 23

615:3x 5x 41

782:2x 17x 23

463:463

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

17x 23 = 391

Therefore, the value for common factors is 391.

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 = 87064200690/(1x391)

LCM = 87064200690/391

LCM = 222670590

Thus, we can understand that the LCM of 391,615,782,463 is 222670590.
