Given numbers are 917,551,646,304
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,551,646,304 is 137432624.
Find LCM of 917,551,646,304 with Prime Factorization
| 2 | 917, 551, 646, 304 |
| 19 | 917, 551, 323, 152 |
| 917, 29, 17, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 917 x 29 x 17 x 8 = 137432624
Therefore, the lowest common multiple of 917,551,646,304 is 137432624.
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.
917 x 551 x 646 x 304 = 99226354528
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.
917 : 1, 7, 131, 917
551 : 1, 19, 29, 551
646 : 1, 2, 17, 19, 34, 38, 323, 646
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,551,646,304, is 1.
Now, the common factors can be found like this.
917:7x 131
551:19x 29
646:2x 17x 19
304:2x 2x 2x 2x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19x 19 = 722
Therefore, the value for common factors is 722.
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 = 99226354528/(1x722)
LCM = 99226354528/722
LCM = 137432624
Thus, we can understand that the LCM of 917,551,646,304 is 137432624.
