Calculate the LCM of 918,205,442,745

Given numbers are 918,205,442,745

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

The LCM of 918,205,442,745 is 364524030.

Find LCM of 918,205,442,745 with Prime Factorization


2 918, 205, 442, 745
5 459, 205, 221, 745
17 459, 41, 221, 149
27, 41, 13, 149

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

2 x 5 x 17 x 27 x 41 x 13 x 149 = 364524030

Therefore, the lowest common multiple of 918,205,442,745 is 364524030.

LCM Formula to Find Lowest Common Multiple of 918,205,442,745

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.

918 x 205 x 442 x 745 = 61969085100

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.

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

205 : 1, 5, 41, 205

442 : 1, 2, 13, 17, 26, 34, 221, 442

745 : 1, 5, 149, 745

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,205,442,745, is 1.

Now, the common factors can be found like this.

918:2x 3x 3x 3x 17

205:5x 41

442:2x 13x 17

745:5x 149

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

2x 5x 17 = 170

Therefore, the value for common factors is 170.

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 = 61969085100/(1x170)

LCM = 61969085100/170

LCM = 364524030

Thus, we can understand that the LCM of 918,205,442,745 is 364524030.
