Given numbers are 961,642,358,688

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

The LCM of 961,642,358,688 is 37990052112.

Find LCM of 961,642,358,688 with Prime Factorization

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

2 x 961 x 321 x 179 x 344 = 37990052112

Therefore, the lowest common multiple of 961,642,358,688 is 37990052112.

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 642 x 358 x 688 = 151960208448

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

642 : 1, 2, 3, 6, 107, 214, 321, 642

358 : 1, 2, 179, 358

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,642,358,688, is 1.

Now, the common factors can be found like this.

961:31x 31

642:2x 3x 107

358:2x 179

688:2x 2x 2x 2x 43

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 151960208448/(1x4)

LCM = 151960208448/4

LCM = 37990052112

Thus, we can understand that the LCM of 961,642,358,688 is 37990052112.
