The LCM of 830,849,147,154,686 is 2658719910.
Find LCM of 830,849,147,154,686 with Prime Factorization
| 2 | 830, 849, 147, 154, 686 |
| 3 | 415, 849, 147, 77, 343 |
| 7 | 415, 283, 49, 77, 343 |
| 7 | 415, 283, 7, 11, 49 |
| 415, 283, 1, 11, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 415 x 283 x 1 x 11 x 7 = 2658719910
Therefore, the lowest common multiple of 830,849,147,154,686 is 2658719910.
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.
830 x 849 x 147 x 154 x 686 = 10943291149560
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.
830 : 1, 2, 5, 10, 83, 166, 415, 830
849 : 1, 3, 283, 849
147 : 1, 3, 7, 21, 49, 147
154 : 1, 2, 7, 11, 14, 22, 77, 154
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,849,147,154,686, is 1.
Now, the common factors can be found like this.
830:2x 5x 83
849:3x 283
147:3x 7x 7
154:2x 7x 11
686:2x 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 2x 3x 7x 7x 7 = 4116
Therefore, the value for common factors is 4116.
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 = 10943291149560/(1x4116)
LCM = 10943291149560/4116
LCM = 2658719910
Thus, we can understand that the LCM of 830,849,147,154,686 is 2658719910.
