Find LCM of 689,891,209,958,528 with Prime Factorization
| 2 | 689, 891, 209, 958, 528 |
| 3 | 689, 891, 209, 479, 264 |
| 11 | 689, 297, 209, 479, 88 |
| 689, 27, 19, 479, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 689 x 27 x 19 x 479 x 8 = 89393516784
Therefore, the lowest common multiple of 689,891,209,958,528 is 89393516784.
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.
689 x 891 x 209 x 958 x 528 = 64899693185184
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.
689 : 1, 13, 53, 689
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
209 : 1, 11, 19, 209
958 : 1, 2, 479, 958
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,891,209,958,528, is 1.
Now, the common factors can be found like this.
689:13x 53
891:3x 3x 3x 3x 11
209:11x 19
958:2x 479
528:2x 2x 2x 2x 3x 11
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 11x 11 = 726
Therefore, the value for common factors is 726.
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 = 64899693185184/(1x726)
LCM = 64899693185184/726
LCM = 89393516784
Thus, we can understand that the LCM of 689,891,209,958,528 is 89393516784.
