Find LCM of 845,387,260,749,107 with Prime Factorization
| 5 | 845, 387, 260, 749, 107 |
| 13 | 169, 387, 52, 749, 107 |
| 107 | 13, 387, 4, 749, 107 |
| 13, 387, 4, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 107 x 13 x 387 x 4 x 7 x 1 = 979736940
Therefore, the lowest common multiple of 845,387,260,749,107 is 979736940.
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.
845 x 387 x 260 x 749 x 107 = 6814070417700
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.
845 : 1, 5, 13, 65, 169, 845
387 : 1, 3, 9, 43, 129, 387
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
749 : 1, 7, 107, 749
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,387,260,749,107, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
387:3x 3x 43
260:2x 2x 5x 13
749:7x 107
107:107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 107 = 6955
Therefore, the value for common factors is 6955.
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 = 6814070417700/(1x6955)
LCM = 6814070417700/6955
LCM = 979736940
Thus, we can understand that the LCM of 845,387,260,749,107 is 979736940.
