The LCM of 370,315,309,644 is 110442780.

Find LCM of 370,315,309,644 with Prime Factorization


2 370, 315, 309, 644
3 185, 315, 309, 322
5 185, 105, 103, 322
7 37, 21, 103, 322
37, 3, 103, 46

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

2 x 3 x 5 x 7 x 37 x 3 x 103 x 46 = 110442780

Therefore, the lowest common multiple of 370,315,309,644 is 110442780.

LCM Formula to Find Lowest Common Multiple of 370,315,309,644

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.

370 x 315 x 309 x 644 = 23192983800

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.

370 : 1, 2, 5, 10, 37, 74, 185, 370

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

309 : 1, 3, 103, 309

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 370,315,309,644, is 1.

Now, the common factors can be found like this.

370:2x 5x 37

315:3x 3x 5x 7

309:3x 103

644:2x 2x 7x 23

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 5x 7 = 210

Therefore, the value for common factors is 210.

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 = 23192983800/(1x210)

LCM = 23192983800/210

LCM = 110442780

Thus, we can understand that the LCM of 370,315,309,644 is 110442780.
