Given numbers are 656,258,445,989

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

The LCM of 656,258,445,989 is 866126640.

Find LCM of 656,258,445,989 with Prime Factorization

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

2 x 43 x 328 x 3 x 445 x 23 = 866126640

Therefore, the lowest common multiple of 656,258,445,989 is 866126640.

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.

656 x 258 x 445 x 989 = 74486891040

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.

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

258 : 1, 2, 3, 6, 43, 86, 129, 258

445 : 1, 5, 89, 445

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,258,445,989, is 1.

Now, the common factors can be found like this.

656:2x 2x 2x 2x 41

258:2x 3x 43

445:5x 89

989:23x 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 43 = 86

Therefore, the value for common factors is 86.

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 = 74486891040/(1x86)

LCM = 74486891040/86

LCM = 866126640

Thus, we can understand that the LCM of 656,258,445,989 is 866126640.
