Given numbers are 749,847,517,913
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,847,517,913 is 353543729.
Find LCM of 749,847,517,913 with Prime Factorization
| 7 | 749, 847, 517, 913 |
| 11 | 107, 121, 517, 913 |
| 107, 11, 47, 83 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 107 x 11 x 47 x 83 = 353543729
Therefore, the lowest common multiple of 749,847,517,913 is 353543729.
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.
749 x 847 x 517 x 913 = 299451538463
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.
749 : 1, 7, 107, 749
847 : 1, 7, 11, 77, 121, 847
517 : 1, 11, 47, 517
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,847,517,913, is 1.
Now, the common factors can be found like this.
749:7x 107
847:7x 11x 11
517:11x 47
913:11x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 11 = 847
Therefore, the value for common factors is 847.
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 = 299451538463/(1x847)
LCM = 299451538463/847
LCM = 353543729
Thus, we can understand that the LCM of 749,847,517,913 is 353543729.
