The LCM of 916,171,665,336 is 21929040.
Find LCM of 916,171,665,336 with Prime Factorization
| 2 | 916, 171, 665, 336 |
| 2 | 458, 171, 665, 168 |
| 3 | 229, 171, 665, 84 |
| 7 | 229, 57, 665, 28 |
| 19 | 229, 57, 95, 4 |
| 229, 3, 5, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 19 x 229 x 3 x 5 x 4 = 21929040
Therefore, the lowest common multiple of 916,171,665,336 is 21929040.
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 171 x 665 x 336 = 34998747840
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
171 : 1, 3, 9, 19, 57, 171
665 : 1, 5, 7, 19, 35, 95, 133, 665
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,171,665,336, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
171:3x 3x 19
665:5x 7x 19
336:2x 2x 2x 2x 3x 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 19 = 1596
Therefore, the value for common factors is 1596.
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 = 34998747840/(1x1596)
LCM = 34998747840/1596
LCM = 21929040
Thus, we can understand that the LCM of 916,171,665,336 is 21929040.
