Find LCM of 616,903,817,646 with Prime Factorization
| 2 | 616, 903, 817, 646 |
| 7 | 308, 903, 817, 323 |
| 19 | 44, 129, 817, 323 |
| 43 | 44, 129, 43, 17 |
| 44, 3, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 43 x 44 x 3 x 1 x 17 = 25666872
Therefore, the lowest common multiple of 616,903,817,646 is 25666872.
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.
616 x 903 x 817 x 646 = 293577681936
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.
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
903 : 1, 3, 7, 21, 43, 129, 301, 903
817 : 1, 19, 43, 817
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,903,817,646, is 1.
Now, the common factors can be found like this.
616:2x 2x 2x 7x 11
903:3x 7x 43
817:19x 43
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 19x 43 = 11438
Therefore, the value for common factors is 11438.
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 = 293577681936/(1x11438)
LCM = 293577681936/11438
LCM = 25666872
Thus, we can understand that the LCM of 616,903,817,646 is 25666872.
