The LCM of 195,481,354,720 is 20432880.

Find LCM of 195,481,354,720 with Prime Factorization


2 195, 481, 354, 720
3 195, 481, 177, 360
5 65, 481, 59, 120
13 13, 481, 59, 24
1, 37, 59, 24

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

2 x 3 x 5 x 13 x 1 x 37 x 59 x 24 = 20432880

Therefore, the lowest common multiple of 195,481,354,720 is 20432880.

LCM Formula to Find Lowest Common Multiple of 195,481,354,720

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.

195 x 481 x 354 x 720 = 23906469600

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.

195 : 1, 3, 5, 13, 15, 39, 65, 195

481 : 1, 13, 37, 481

354 : 1, 2, 3, 6, 59, 118, 177, 354

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 195,481,354,720, is 1.

Now, the common factors can be found like this.

195:3x 5x 13

481:13x 37

354:2x 3x 59

720:2x 2x 2x 2x 3x 3x 5

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 5x 13 = 1170

Therefore, the value for common factors is 1170.

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 = 23906469600/(1x1170)

LCM = 23906469600/1170

LCM = 20432880

Thus, we can understand that the LCM of 195,481,354,720 is 20432880.
