Find LCM of 916,258,690,109,920 with Prime Factorization
| 2 | 916, 258, 690, 109, 920 |
| 2 | 458, 129, 345, 109, 460 |
| 3 | 229, 129, 345, 109, 230 |
| 5 | 229, 43, 115, 109, 230 |
| 23 | 229, 43, 23, 109, 46 |
| 229, 43, 1, 109, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 23 x 229 x 43 x 1 x 109 x 2 = 2962371480
Therefore, the lowest common multiple of 916,258,690,109,920 is 2962371480.
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.
916 x 258 x 690 x 109 x 920 = 16352290569600
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.
916 : 1, 2, 4, 229, 458, 916
258 : 1, 2, 3, 6, 43, 86, 129, 258
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
109 : 1, 109
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,258,690,109,920, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
258:2x 3x 43
690:2x 3x 5x 23
109:109
920:2x 2x 2x 5x 23
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 3x 5x 23 = 5520
Therefore, the value for common factors is 5520.
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 = 16352290569600/(1x5520)
LCM = 16352290569600/5520
LCM = 2962371480
Thus, we can understand that the LCM of 916,258,690,109,920 is 2962371480.
