Calculate the LCM of 741,165,390

Given numbers are 741,165,390

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

The LCM of 741,165,390 is 81510.

Find LCM of 741,165,390 with Prime Factorization


3 741, 165, 390
5 247, 55, 130
13 247, 11, 26
19, 11, 2

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

3 x 5 x 13 x 19 x 11 x 2 = 81510

Therefore, the lowest common multiple of 741,165,390 is 81510.

LCM Formula to Find Lowest Common Multiple of 741,165,390

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.

741 x 165 x 390 = 47683350

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.

741 : 1, 3, 13, 19, 39, 57, 247, 741

165 : 1, 3, 5, 11, 15, 33, 55, 165

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,165,390, is 3.

Now, the common factors can be found like this.

741:3x 13x 19

165:3x 5x 11

390:2x 3x 5x 13

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

3x 5x 13 = 195

Therefore, the value for common factors is 195.

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 = 47683350/(3x195)

LCM = 47683350/585

LCM = 81510

Thus, we can understand that the LCM of 741,165,390 is 81510.
