Given numbers are 169,716,157,428,343
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,716,157,428,343 is 697231945228.
Find LCM of 169,716,157,428,343 with Prime Factorization
| 2 | 169, 716, 157, 428, 343 |
| 2 | 169, 358, 157, 214, 343 |
| 169, 179, 157, 107, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 169 x 179 x 157 x 107 x 343 = 697231945228
Therefore, the lowest common multiple of 169,716,157,428,343 is 697231945228.
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 716 x 157 x 428 x 343 = 2788927780912
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
716 : 1, 2, 4, 179, 358, 716
157 : 1, 157
428 : 1, 2, 4, 107, 214, 428
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,716,157,428,343, is 1.
Now, the common factors can be found like this.
169:13x 13
716:2x 2x 179
157:157
428:2x 2x 107
343:7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 2788927780912/(1x4)
LCM = 2788927780912/4
LCM = 697231945228
Thus, we can understand that the LCM of 169,716,157,428,343 is 697231945228.
