Find LCM of 387,880,791,840,170 with Prime Factorization
| 2 | 387, 880, 791, 840, 170 |
| 2 | 387, 440, 791, 420, 85 |
| 2 | 387, 220, 791, 210, 85 |
| 3 | 387, 110, 791, 105, 85 |
| 5 | 129, 110, 791, 35, 85 |
| 7 | 129, 22, 791, 7, 17 |
| 129, 22, 113, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 129 x 22 x 113 x 1 x 17 = 4579510320
Therefore, the lowest common multiple of 387,880,791,840,170 is 4579510320.
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.
387 x 880 x 791 x 840 x 170 = 38467886688000
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.
387 : 1, 3, 9, 43, 129, 387
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
791 : 1, 7, 113, 791
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
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,880,791,840,170, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
880:2x 2x 2x 2x 5x 11
791:7x 113
840:2x 2x 2x 3x 5x 7
170:2x 5x 17
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 5x 7 = 8400
Therefore, the value for common factors is 8400.
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 = 38467886688000/(1x8400)
LCM = 38467886688000/8400
LCM = 4579510320
Thus, we can understand that the LCM of 387,880,791,840,170 is 4579510320.
