Calculate the LCM of 344,645,669,378,957

Given numbers are 344,645,669,378,957

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

The LCM of 344,645,669,378,957 is 23125215960.

Find LCM of 344,645,669,378,957 with Prime Factorization


2 344, 645, 669, 378, 957
3 172, 645, 669, 189, 957
43 172, 215, 223, 63, 319
4, 5, 223, 63, 319

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

2 x 3 x 43 x 4 x 5 x 223 x 63 x 319 = 23125215960

Therefore, the lowest common multiple of 344,645,669,378,957 is 23125215960.

LCM Formula to Find Lowest Common Multiple of 344,645,669,378,957

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.

344 x 645 x 669 x 378 x 957 = 53696751459120

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.

344 : 1, 2, 4, 8, 43, 86, 172, 344

645 : 1, 3, 5, 15, 43, 129, 215, 645

669 : 1, 3, 223, 669

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

957 : 1, 3, 11, 29, 33, 87, 319, 957

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 344,645,669,378,957, is 1.

Now, the common factors can be found like this.

344:2x 2x 2x 43

645:3x 5x 43

669:3x 223

378:2x 3x 3x 3x 7

957:3x 11x 29

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 3x 43 = 2322

Therefore, the value for common factors is 2322.

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 = 53696751459120/(1x2322)

LCM = 53696751459120/2322

LCM = 23125215960

Thus, we can understand that the LCM of 344,645,669,378,957 is 23125215960.
