Find LCM of 140,834,803,880,287 with Prime Factorization
| 2 | 140, 834, 803, 880, 287 |
| 2 | 70, 417, 803, 440, 287 |
| 5 | 35, 417, 803, 220, 287 |
| 7 | 7, 417, 803, 44, 287 |
| 11 | 1, 417, 803, 44, 41 |
| 1, 417, 73, 4, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 11 x 1 x 417 x 73 x 4 x 41 = 7688178960
Therefore, the lowest common multiple of 140,834,803,880,287 is 7688178960.
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.
140 x 834 x 803 x 880 x 287 = 23679591196800
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
834 : 1, 2, 3, 6, 139, 278, 417, 834
803 : 1, 11, 73, 803
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,834,803,880,287, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
834:2x 3x 139
803:11x 73
880:2x 2x 2x 2x 5x 11
287:7x 41
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 5x 7x 11 = 3080
Therefore, the value for common factors is 3080.
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 = 23679591196800/(1x3080)
LCM = 23679591196800/3080
LCM = 7688178960
Thus, we can understand that the LCM of 140,834,803,880,287 is 7688178960.
