Given numbers are 645,117,679,889,258

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

The LCM of 645,117,679,889,258 is 4338382230.

Find LCM of 645,117,679,889,258 with Prime Factorization

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

3 x 7 x 43 x 5 x 39 x 97 x 127 x 2 = 4338382230

Therefore, the lowest common multiple of 645,117,679,889,258 is 4338382230.

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.

645 x 117 x 679 x 889 x 258 = 11752677461070

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

117 : 1, 3, 9, 13, 39, 117

679 : 1, 7, 97, 679

889 : 1, 7, 127, 889

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,117,679,889,258, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

117:3x 3x 13

679:7x 97

889:7x 127

258:2x 3x 43

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

3x 3x 7x 43 = 2709

Therefore, the value for common factors is 2709.

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 = 11752677461070/(1x2709)

LCM = 11752677461070/2709

LCM = 4338382230

Thus, we can understand that the LCM of 645,117,679,889,258 is 4338382230.
