Find LCM of 424,176,721,357,870 with Prime Factorization
| 2 | 424, 176, 721, 357, 870 |
| 2 | 212, 88, 721, 357, 435 |
| 2 | 106, 44, 721, 357, 435 |
| 3 | 53, 22, 721, 357, 435 |
| 7 | 53, 22, 721, 119, 145 |
| 53, 22, 103, 17, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 53 x 22 x 103 x 17 x 145 = 49734983760
Therefore, the lowest common multiple of 424,176,721,357,870 is 49734983760.
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.
424 x 176 x 721 x 357 x 870 = 16710954543360
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.
424 : 1, 2, 4, 8, 53, 106, 212, 424
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
721 : 1, 7, 103, 721
357 : 1, 3, 7, 17, 21, 51, 119, 357
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,176,721,357,870, is 1.
Now, the common factors can be found like this.
424:2x 2x 2x 53
176:2x 2x 2x 2x 11
721:7x 103
357:3x 7x 17
870:2x 3x 5x 29
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 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 16710954543360/(1x336)
LCM = 16710954543360/336
LCM = 49734983760
Thus, we can understand that the LCM of 424,176,721,357,870 is 49734983760.
