Find LCM of 160,771,840,894,812 with Prime Factorization
| 2 | 160, 771, 840, 894, 812 |
| 2 | 80, 771, 420, 447, 406 |
| 2 | 40, 771, 210, 447, 203 |
| 3 | 20, 771, 105, 447, 203 |
| 5 | 20, 257, 35, 149, 203 |
| 7 | 4, 257, 7, 149, 203 |
| 4, 257, 1, 149, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 4 x 257 x 1 x 149 x 29 = 3731269920
Therefore, the lowest common multiple of 160,771,840,894,812 is 3731269920.
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.
160 x 771 x 840 x 894 x 812 = 75222401587200
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.
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
771 : 1, 3, 257, 771
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
894 : 1, 2, 3, 6, 149, 298, 447, 894
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 160,771,840,894,812, is 1.
Now, the common factors can be found like this.
160:2x 2x 2x 2x 2x 5
771:3x 257
840:2x 2x 2x 3x 5x 7
894:2x 3x 149
812:2x 2x 7x 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 2x 2x 3x 3x 5x 7 = 20160
Therefore, the value for common factors is 20160.
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 = 75222401587200/(1x20160)
LCM = 75222401587200/20160
LCM = 3731269920
Thus, we can understand that the LCM of 160,771,840,894,812 is 3731269920.
