Calculate the LCM of 155,138,138,849

Given numbers are 155,138,138,849

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

The LCM of 155,138,138,849 is 6053370.

Find LCM of 155,138,138,849 with Prime Factorization


2 155, 138, 138, 849
3 155, 69, 69, 849
23 155, 23, 23, 283
155, 1, 1, 283

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

2 x 3 x 23 x 155 x 1 x 1 x 283 = 6053370

Therefore, the lowest common multiple of 155,138,138,849 is 6053370.

LCM Formula to Find Lowest Common Multiple of 155,138,138,849

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.

155 x 138 x 138 x 849 = 2506095180

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.

155 : 1, 5, 31, 155

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

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

849 : 1, 3, 283, 849

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,138,138,849, is 1.

Now, the common factors can be found like this.

155:5x 31

138:2x 3x 23

138:2x 3x 23

849:3x 283

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 23 = 414

Therefore, the value for common factors is 414.

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 = 2506095180/(1x414)

LCM = 2506095180/414

LCM = 6053370

Thus, we can understand that the LCM of 155,138,138,849 is 6053370.
