Given numbers are 918,215,515,560

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

The LCM of 918,215,515,560 is 1138430160.

Find LCM of 918,215,515,560 with Prime Factorization


2 918, 215, 515, 560
5 459, 215, 515, 280
459, 43, 103, 56

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

2 x 5 x 459 x 43 x 103 x 56 = 1138430160

Therefore, the lowest common multiple of 918,215,515,560 is 1138430160.

LCM Formula to Find Lowest Common Multiple of 918,215,515,560

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 215 x 515 x 560 = 56921508000

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

215 : 1, 5, 43, 215

515 : 1, 5, 103, 515

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,215,515,560, is 1.

Now, the common factors can be found like this.

918:2x 3x 3x 3x 17

215:5x 43

515:5x 103

560:2x 2x 2x 2x 5x 7

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 5 = 50

Therefore, the value for common factors is 50.

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 = 56921508000/(1x50)

LCM = 56921508000/50

LCM = 1138430160

Thus, we can understand that the LCM of 918,215,515,560 is 1138430160.
