Given numbers are 426,284,865,491

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

The LCM of 426,284,865,491 is 361857180.

Find LCM of 426,284,865,491 with Prime Factorization

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

2 x 71 x 3 x 2 x 865 x 491 = 361857180

Therefore, the lowest common multiple of 426,284,865,491 is 361857180.

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.

426 x 284 x 865 x 491 = 51383719560

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.

426 : 1, 2, 3, 6, 71, 142, 213, 426

284 : 1, 2, 4, 71, 142, 284

865 : 1, 5, 173, 865

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,284,865,491, is 1.

Now, the common factors can be found like this.

426:2x 3x 71

284:2x 2x 71

865:5x 173

491:491

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

2x 71 = 142

Therefore, the value for common factors is 142.

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 = 51383719560/(1x142)

LCM = 51383719560/142

LCM = 361857180

Thus, we can understand that the LCM of 426,284,865,491 is 361857180.
