Find LCM of 169,646,741,716,312 with Prime Factorization
| 2 | 169, 646, 741, 716, 312 |
| 2 | 169, 323, 741, 358, 156 |
| 3 | 169, 323, 741, 179, 78 |
| 13 | 169, 323, 247, 179, 26 |
| 19 | 13, 323, 19, 179, 2 |
| 13, 17, 1, 179, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 19 x 13 x 17 x 1 x 179 x 2 = 234505752
Therefore, the lowest common multiple of 169,646,741,716,312 is 234505752.
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.
169 x 646 x 741 x 716 x 312 = 18071951272128
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.
169 : 1, 13, 169
646 : 1, 2, 17, 19, 34, 38, 323, 646
741 : 1, 3, 13, 19, 39, 57, 247, 741
716 : 1, 2, 4, 179, 358, 716
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,646,741,716,312, is 1.
Now, the common factors can be found like this.
169:13x 13
646:2x 17x 19
741:3x 13x 19
716:2x 2x 179
312:2x 2x 2x 3x 13
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 3x 13x 13x 19 = 77064
Therefore, the value for common factors is 77064.
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 = 18071951272128/(1x77064)
LCM = 18071951272128/77064
LCM = 234505752
Thus, we can understand that the LCM of 169,646,741,716,312 is 234505752.
