Find LCM of 289,868,726,581,341 with Prime Factorization
| 2 | 289, 868, 726, 581, 341 |
| 7 | 289, 434, 363, 581, 341 |
| 11 | 289, 62, 363, 83, 341 |
| 31 | 289, 62, 33, 83, 31 |
| 289, 2, 33, 83, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 31 x 289 x 2 x 33 x 83 x 1 = 7557919908
Therefore, the lowest common multiple of 289,868,726,581,341 is 7557919908.
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.
289 x 868 x 726 x 581 x 341 = 36081509640792
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.
289 : 1, 17, 289
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
581 : 1, 7, 83, 581
341 : 1, 11, 31, 341
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,868,726,581,341, is 1.
Now, the common factors can be found like this.
289:17x 17
868:2x 2x 7x 31
726:2x 3x 11x 11
581:7x 83
341:11x 31
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 11x 31 = 4774
Therefore, the value for common factors is 4774.
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 = 36081509640792/(1x4774)
LCM = 36081509640792/4774
LCM = 7557919908
Thus, we can understand that the LCM of 289,868,726,581,341 is 7557919908.
