Given numbers are 961,581,687,415

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

The LCM of 961,581,687,415 is 1917901335.

Find LCM of 961,581,687,415 with Prime Factorization

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

83 x 961 x 7 x 687 x 5 = 1917901335

Therefore, the lowest common multiple of 961,581,687,415 is 1917901335.

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.

961 x 581 x 687 x 415 = 159185810805

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.

961 : 1, 31, 961

581 : 1, 7, 83, 581

687 : 1, 3, 229, 687

415 : 1, 5, 83, 415

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,581,687,415, is 1.

Now, the common factors can be found like this.

961:31x 31

581:7x 83

687:3x 229

415:5x 83

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

83 = 83

Therefore, the value for common factors is 83.

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 = 159185810805/(1x83)

LCM = 159185810805/83

LCM = 1917901335

Thus, we can understand that the LCM of 961,581,687,415 is 1917901335.
