Given numbers are 748,913,912,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 748,913,912,648 is 382189104.
Find LCM of 748,913,912,648 with Prime Factorization
| 2 | 748, 913, 912, 648 |
| 2 | 374, 913, 456, 324 |
| 2 | 187, 913, 228, 162 |
| 3 | 187, 913, 114, 81 |
| 11 | 187, 913, 38, 27 |
| 17, 83, 38, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 17 x 83 x 38 x 27 = 382189104
Therefore, the lowest common multiple of 748,913,912,648 is 382189104.
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.
748 x 913 x 912 x 648 = 403591693824
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
913 : 1, 11, 83, 913
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,913,912,648, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
913:11x 83
912:2x 2x 2x 2x 3x 19
648:2x 2x 2x 3x 3x 3x 3
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 2x 3x 11 = 1056
Therefore, the value for common factors is 1056.
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 = 403591693824/(1x1056)
LCM = 403591693824/1056
LCM = 382189104
Thus, we can understand that the LCM of 748,913,912,648 is 382189104.
