Find LCM of 669,158,560,840,576 with Prime Factorization
| 2 | 669, 158, 560, 840, 576 |
| 2 | 669, 79, 280, 420, 288 |
| 2 | 669, 79, 140, 210, 144 |
| 2 | 669, 79, 70, 105, 72 |
| 3 | 669, 79, 35, 105, 36 |
| 5 | 223, 79, 35, 35, 12 |
| 7 | 223, 79, 7, 7, 12 |
| 223, 79, 1, 1, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 7 x 223 x 79 x 1 x 1 x 12 = 355158720
Therefore, the lowest common multiple of 669,158,560,840,576 is 355158720.
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.
669 x 158 x 560 x 840 x 576 = 28639999180800
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.
669 : 1, 3, 223, 669
158 : 1, 2, 79, 158
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
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
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,158,560,840,576, is 1.
Now, the common factors can be found like this.
669:3x 223
158:2x 79
560:2x 2x 2x 2x 5x 7
840:2x 2x 2x 3x 5x 7
576:2x 2x 2x 2x 2x 2x 3x 3
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 2x 2x 3x 3x 5x 7 = 80640
Therefore, the value for common factors is 80640.
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 = 28639999180800/(1x80640)
LCM = 28639999180800/80640
LCM = 355158720
Thus, we can understand that the LCM of 669,158,560,840,576 is 355158720.
