Find LCM of 840,500,671,105,186 with Prime Factorization
| 2 | 840, 500, 671, 105, 186 |
| 2 | 420, 250, 671, 105, 93 |
| 3 | 210, 125, 671, 105, 93 |
| 5 | 70, 125, 671, 35, 31 |
| 7 | 14, 25, 671, 7, 31 |
| 2, 25, 671, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 2 x 25 x 671 x 1 x 31 = 436821000
Therefore, the lowest common multiple of 840,500,671,105,186 is 436821000.
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.
840 x 500 x 671 x 105 x 186 = 5503944600000
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.
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
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
671 : 1, 11, 61, 671
105 : 1, 3, 5, 7, 15, 21, 35, 105
186 : 1, 2, 3, 6, 31, 62, 93, 186
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,500,671,105,186, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
500:2x 2x 5x 5x 5
671:11x 61
105:3x 5x 7
186:2x 3x 31
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 3x 3x 5x 5x 7 = 12600
Therefore, the value for common factors is 12600.
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 = 5503944600000/(1x12600)
LCM = 5503944600000/12600
LCM = 436821000
Thus, we can understand that the LCM of 840,500,671,105,186 is 436821000.
