Find LCM of 210,687,917,294,841 with Prime Factorization
| 2 | 210, 687, 917, 294, 841 |
| 3 | 105, 687, 917, 147, 841 |
| 7 | 35, 229, 917, 49, 841 |
| 5, 229, 131, 7, 841 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 5 x 229 x 131 x 7 x 841 = 37086863730
Therefore, the lowest common multiple of 210,687,917,294,841 is 37086863730.
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.
210 x 687 x 917 x 294 x 841 = 32710613809860
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.
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
687 : 1, 3, 229, 687
917 : 1, 7, 131, 917
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,687,917,294,841, is 1.
Now, the common factors can be found like this.
210:2x 3x 5x 7
687:3x 229
917:7x 131
294:2x 3x 7x 7
841:29x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 7 = 882
Therefore, the value for common factors is 882.
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 = 32710613809860/(1x882)
LCM = 32710613809860/882
LCM = 37086863730
Thus, we can understand that the LCM of 210,687,917,294,841 is 37086863730.
