Given numbers are 609,399,396,138

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

The LCM of 609,399,396,138 is 35129556.

Find LCM of 609,399,396,138 with Prime Factorization


2 609, 399, 396, 138
3 609, 399, 198, 69
7 203, 133, 66, 23
29, 19, 66, 23

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

2 x 3 x 7 x 29 x 19 x 66 x 23 = 35129556

Therefore, the lowest common multiple of 609,399,396,138 is 35129556.

LCM Formula to Find Lowest Common Multiple of 609,399,396,138

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.

609 x 399 x 396 x 138 = 13278972168

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.

609 : 1, 3, 7, 21, 29, 87, 203, 609

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

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

138 : 1, 2, 3, 6, 23, 46, 69, 138

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,399,396,138, is 3.

Now, the common factors can be found like this.

609:3x 7x 29

399:3x 7x 19

396:2x 2x 3x 3x 11

138:2x 3x 23

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

2x 3x 3x 7 = 126

Therefore, the value for common factors is 126.

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 = 13278972168/(3x126)

LCM = 13278972168/378

LCM = 35129556

Thus, we can understand that the LCM of 609,399,396,138 is 35129556.
