Given numbers are 197,258,756,906,561

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

The LCM of 197,258,756,906,561 is 180831894012.

Find LCM of 197,258,756,906,561 with Prime Factorization

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

2 x 3 x 197 x 43 x 126 x 151 x 187 = 180831894012

Therefore, the lowest common multiple of 197,258,756,906,561 is 180831894012.

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.

197 x 258 x 756 x 906 x 561 = 19529844553296

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.

197 : 1, 197

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

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

906 : 1, 2, 3, 6, 151, 302, 453, 906

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,258,756,906,561, is 1.

Now, the common factors can be found like this.

197:197

258:2x 3x 43

756:2x 2x 3x 3x 3x 7

906:2x 3x 151

561:3x 11x 17

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

2x 2x 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 19529844553296/(1x108)

LCM = 19529844553296/108

LCM = 180831894012

Thus, we can understand that the LCM of 197,258,756,906,561 is 180831894012.
