Given numbers are 687,856,421,149,963

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

The LCM of 687,856,421,149,963 is 110667505464.

Find LCM of 687,856,421,149,963 with Prime Factorization

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

3 x 107 x 229 x 8 x 421 x 149 x 3 = 110667505464

Therefore, the lowest common multiple of 687,856,421,149,963 is 110667505464.

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.

687 x 856 x 421 x 149 x 963 = 35524269253944

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.

687 : 1, 3, 229, 687

856 : 1, 2, 4, 8, 107, 214, 428, 856

421 : 1, 421

149 : 1, 149

963 : 1, 3, 9, 107, 321, 963

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,856,421,149,963, is 1.

Now, the common factors can be found like this.

687:3x 229

856:2x 2x 2x 107

421:421

149:149

963:3x 3x 107

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

3x 107 = 321

Therefore, the value for common factors is 321.

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 = 35524269253944/(1x321)

LCM = 35524269253944/321

LCM = 110667505464

Thus, we can understand that the LCM of 687,856,421,149,963 is 110667505464.
