Given numbers are 781,318,266,432,386

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

The LCM of 781,318,266,432,386 is 459007308144.

Find LCM of 781,318,266,432,386 with Prime Factorization

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

2 x 3 x 781 x 53 x 133 x 72 x 193 = 459007308144

Therefore, the lowest common multiple of 781,318,266,432,386 is 459007308144.

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.

781 x 318 x 266 x 432 x 386 = 11016175395456

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.

781 : 1, 11, 71, 781

318 : 1, 2, 3, 6, 53, 106, 159, 318

266 : 1, 2, 7, 14, 19, 38, 133, 266

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,318,266,432,386, is 1.

Now, the common factors can be found like this.

781:11x 71

318:2x 3x 53

266:2x 7x 19

432:2x 2x 2x 2x 3x 3x 3

386:2x 193

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

2x 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 11016175395456/(1x24)

LCM = 11016175395456/24

LCM = 459007308144

Thus, we can understand that the LCM of 781,318,266,432,386 is 459007308144.
