Calculate the LCM of 345,247,644,218

Given numbers are 345,247,644,218

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

The LCM of 345,247,644,218 is 260076180.

Find LCM of 345,247,644,218 with Prime Factorization


2 345, 247, 644, 218
23 345, 247, 322, 109
15, 247, 14, 109

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

2 x 23 x 15 x 247 x 14 x 109 = 260076180

Therefore, the lowest common multiple of 345,247,644,218 is 260076180.

LCM Formula to Find Lowest Common Multiple of 345,247,644,218

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.

345 x 247 x 644 x 218 = 11963504280

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

247 : 1, 13, 19, 247

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,247,644,218, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

247:13x 19

644:2x 2x 7x 23

218:2x 109

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 11963504280/(1x46)

LCM = 11963504280/46

LCM = 260076180

Thus, we can understand that the LCM of 345,247,644,218 is 260076180.
