Find LCM of 175,808,840,942 with Prime Factorization
| 2 | 175, 808, 840, 942 |
| 2 | 175, 404, 420, 471 |
| 2 | 175, 202, 210, 471 |
| 3 | 175, 101, 105, 471 |
| 5 | 175, 101, 35, 157 |
| 7 | 7, 101, 35, 157 |
| 1, 101, 5, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 1 x 101 x 5 x 157 = 66599400
Therefore, the lowest common multiple of 175,808,840,942 is 66599400.
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.
175 x 808 x 840 x 942 = 111886992000
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.
175 : 1, 5, 7, 25, 35, 175
808 : 1, 2, 4, 8, 101, 202, 404, 808
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 175,808,840,942, is 1.
Now, the common factors can be found like this.
175:5x 5x 7
808:2x 2x 2x 101
840:2x 2x 2x 3x 5x 7
942:2x 3x 157
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 5x 7 = 1680
Therefore, the value for common factors is 1680.
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 = 111886992000/(1x1680)
LCM = 111886992000/1680
LCM = 66599400
Thus, we can understand that the LCM of 175,808,840,942 is 66599400.
