Find LCM of 137,342,832,155,285 with Prime Factorization
| 2 | 137, 342, 832, 155, 285 |
| 3 | 137, 171, 416, 155, 285 |
| 5 | 137, 57, 416, 155, 95 |
| 19 | 137, 57, 416, 31, 19 |
| 137, 3, 416, 31, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 137 x 3 x 416 x 31 x 1 = 3021145920
Therefore, the lowest common multiple of 137,342,832,155,285 is 3021145920.
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.
137 x 342 x 832 x 155 x 285 = 1722053174400
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.
137 : 1, 137
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
155 : 1, 5, 31, 155
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,342,832,155,285, is 1.
Now, the common factors can be found like this.
137:137
342:2x 3x 3x 19
832:2x 2x 2x 2x 2x 2x 13
155:5x 31
285:3x 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 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 = 1722053174400/(1x570)
LCM = 1722053174400/570
LCM = 3021145920
Thus, we can understand that the LCM of 137,342,832,155,285 is 3021145920.
