Given numbers are 786,491,813,249

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

The LCM of 786,491,813,249 is 8680633518.

Find LCM of 786,491,813,249 with Prime Factorization

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

3 x 262 x 491 x 271 x 83 = 8680633518

Therefore, the lowest common multiple of 786,491,813,249 is 8680633518.

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.

786 x 491 x 813 x 249 = 78125701662

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.

786 : 1, 2, 3, 6, 131, 262, 393, 786

491 : 1, 491

813 : 1, 3, 271, 813

249 : 1, 3, 83, 249

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,491,813,249, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

491:491

813:3x 271

249:3x 83

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 78125701662/(1x9)

LCM = 78125701662/9

LCM = 8680633518

Thus, we can understand that the LCM of 786,491,813,249 is 8680633518.
