Find LCM of 343,418,615,988,555 with Prime Factorization
| 2 | 343, 418, 615, 988, 555 |
| 3 | 343, 209, 615, 494, 555 |
| 5 | 343, 209, 205, 494, 185 |
| 19 | 343, 209, 41, 494, 37 |
| 343, 11, 41, 26, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 343 x 11 x 41 x 26 x 37 = 84824359620
Therefore, the lowest common multiple of 343,418,615,988,555 is 84824359620.
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.
343 x 418 x 615 x 988 x 555 = 48349884983400
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.
343 : 1, 7, 49, 343
418 : 1, 2, 11, 19, 22, 38, 209, 418
615 : 1, 3, 5, 15, 41, 123, 205, 615
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
555 : 1, 3, 5, 15, 37, 111, 185, 555
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,418,615,988,555, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
418:2x 11x 19
615:3x 5x 41
988:2x 2x 13x 19
555:3x 5x 37
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 19 = 570
Therefore, the value for common factors is 570.
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 = 48349884983400/(1x570)
LCM = 48349884983400/570
LCM = 84824359620
Thus, we can understand that the LCM of 343,418,615,988,555 is 84824359620.
