The LCM of 247,845,343,380 is 22027460.

Find LCM of 247,845,343,380 with Prime Factorization


5 247, 845, 343, 380
13 247, 169, 343, 76
19 19, 13, 343, 76
1, 13, 343, 4

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

5 x 13 x 19 x 1 x 13 x 343 x 4 = 22027460

Therefore, the lowest common multiple of 247,845,343,380 is 22027460.

LCM Formula to Find Lowest Common Multiple of 247,845,343,380

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.

247 x 845 x 343 x 380 = 27203913100

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.

247 : 1, 13, 19, 247

845 : 1, 5, 13, 65, 169, 845

343 : 1, 7, 49, 343

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,845,343,380, is 1.

Now, the common factors can be found like this.

247:13x 19

845:5x 13x 13

343:7x 7x 7

380:2x 2x 5x 19

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

5x 13x 19 = 1235

Therefore, the value for common factors is 1235.

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 = 27203913100/(1x1235)

LCM = 27203913100/1235

LCM = 22027460

Thus, we can understand that the LCM of 247,845,343,380 is 22027460.
