Find LCM of 232,917,420,176,642 with Prime Factorization
| 2 | 232, 917, 420, 176, 642 |
| 2 | 116, 917, 210, 88, 321 |
| 2 | 58, 917, 105, 44, 321 |
| 3 | 29, 917, 105, 22, 321 |
| 7 | 29, 917, 35, 22, 107 |
| 29, 131, 5, 22, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 29 x 131 x 5 x 22 x 107 = 7511990640
Therefore, the lowest common multiple of 232,917,420,176,642 is 7511990640.
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.
232 x 917 x 420 x 176 x 642 = 10096115420160
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.
232 : 1, 2, 4, 8, 29, 58, 116, 232
917 : 1, 7, 131, 917
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 232,917,420,176,642, is 1.
Now, the common factors can be found like this.
232:2x 2x 2x 29
917:7x 131
420:2x 2x 3x 5x 7
176:2x 2x 2x 2x 11
642:2x 3x 107
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 2x 2x 2x 2x 3x 7 = 1344
Therefore, the value for common factors is 1344.
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 = 10096115420160/(1x1344)
LCM = 10096115420160/1344
LCM = 7511990640
Thus, we can understand that the LCM of 232,917,420,176,642 is 7511990640.
