Find LCM of 272,689,936,820 with Prime Factorization
| 2 | 272, 689, 936, 820 |
| 2 | 136, 689, 468, 410 |
| 2 | 68, 689, 234, 205 |
| 13 | 34, 689, 117, 205 |
| 34, 53, 9, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 34 x 53 x 9 x 205 = 345767760
Therefore, the lowest common multiple of 272,689,936,820 is 345767760.
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.
272 x 689 x 936 x 820 = 143839388160
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.
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
689 : 1, 13, 53, 689
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,689,936,820, is 1.
Now, the common factors can be found like this.
272:2x 2x 2x 2x 17
689:13x 53
936:2x 2x 2x 3x 3x 13
820:2x 2x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 13 = 416
Therefore, the value for common factors is 416.
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 = 143839388160/(1x416)
LCM = 143839388160/416
LCM = 345767760
Thus, we can understand that the LCM of 272,689,936,820 is 345767760.
