Find LCM of 140,917,748,345,803 with Prime Factorization
| 2 | 140, 917, 748, 345, 803 |
| 2 | 70, 917, 374, 345, 803 |
| 5 | 35, 917, 187, 345, 803 |
| 7 | 7, 917, 187, 69, 803 |
| 11 | 1, 131, 187, 69, 803 |
| 1, 131, 17, 69, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 11 x 1 x 131 x 17 x 69 x 73 = 17274794460
Therefore, the lowest common multiple of 140,917,748,345,803 is 17274794460.
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 917 x 748 x 345 x 803 = 26603183468400
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
917 : 1, 7, 131, 917
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
345 : 1, 3, 5, 15, 23, 69, 115, 345
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,917,748,345,803, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
917:7x 131
748:2x 2x 11x 17
345:3x 5x 23
803:11x 73
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 5x 7x 11 = 1540
Therefore, the value for common factors is 1540.
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 = 26603183468400/(1x1540)
LCM = 26603183468400/1540
LCM = 17274794460
Thus, we can understand that the LCM of 140,917,748,345,803 is 17274794460.
