Given numbers are 618,949,561,399,171

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

The LCM of 618,949,561,399,171 is 43759181466.

Find LCM of 618,949,561,399,171 with Prime Factorization

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

3 x 19 x 206 x 949 x 187 x 7 x 3 = 43759181466

Therefore, the lowest common multiple of 618,949,561,399,171 is 43759181466.

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.

618 x 949 x 561 x 399 x 171 = 22448460092058

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.

618 : 1, 2, 3, 6, 103, 206, 309, 618

949 : 1, 13, 73, 949

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

399 : 1, 3, 7, 19, 21, 57, 133, 399

171 : 1, 3, 9, 19, 57, 171

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,949,561,399,171, is 1.

Now, the common factors can be found like this.

618:2x 3x 103

949:13x 73

561:3x 11x 17

399:3x 7x 19

171:3x 3x 19

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 3x 19 = 513

Therefore, the value for common factors is 513.

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 = 22448460092058/(1x513)

LCM = 22448460092058/513

LCM = 43759181466

Thus, we can understand that the LCM of 618,949,561,399,171 is 43759181466.
