Find LCM of 169,170,646,784,416 with Prime Factorization
| 2 | 169, 170, 646, 784, 416 |
| 2 | 169, 85, 323, 392, 208 |
| 2 | 169, 85, 323, 196, 104 |
| 2 | 169, 85, 323, 98, 52 |
| 13 | 169, 85, 323, 49, 26 |
| 17 | 13, 85, 323, 49, 2 |
| 13, 5, 19, 49, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 13 x 17 x 13 x 5 x 19 x 49 x 2 = 427962080
Therefore, the lowest common multiple of 169,170,646,784,416 is 427962080.
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 170 x 646 x 784 x 416 = 6053095659520
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
170 : 1, 2, 5, 10, 17, 34, 85, 170
646 : 1, 2, 17, 19, 34, 38, 323, 646
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,170,646,784,416, is 1.
Now, the common factors can be found like this.
169:13x 13
170:2x 5x 17
646:2x 17x 19
784:2x 2x 2x 2x 7x 7
416:2x 2x 2x 2x 2x 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 2x 2x 2x 13x 17 = 14144
Therefore, the value for common factors is 14144.
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 = 6053095659520/(1x14144)
LCM = 6053095659520/14144
LCM = 427962080
Thus, we can understand that the LCM of 169,170,646,784,416 is 427962080.
