Find LCM of 371,612,988,855 with Prime Factorization
| 2 | 371, 612, 988, 855 |
| 2 | 371, 306, 494, 855 |
| 3 | 371, 153, 247, 855 |
| 3 | 371, 51, 247, 285 |
| 19 | 371, 17, 247, 95 |
| 371, 17, 13, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 371 x 17 x 13 x 5 = 280409220
Therefore, the lowest common multiple of 371,612,988,855 is 280409220.
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.
371 x 612 x 988 x 855 = 191799906480
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.
371 : 1, 7, 53, 371
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 371,612,988,855, is 1.
Now, the common factors can be found like this.
371:7x 53
612:2x 2x 3x 3x 17
988:2x 2x 13x 19
855:3x 3x 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.
2x 2x 3x 3x 19 = 684
Therefore, the value for common factors is 684.
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 = 191799906480/(1x684)
LCM = 191799906480/684
LCM = 280409220
Thus, we can understand that the LCM of 371,612,988,855 is 280409220.
