Given numbers are 814,414,904,253,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,414,904,253,991 is 75475646136.
Find LCM of 814,414,904,253,991 with Prime Factorization
| 2 | 814, 414, 904, 253, 991 |
| 11 | 407, 207, 452, 253, 991 |
| 23 | 37, 207, 452, 23, 991 |
| 37, 9, 452, 1, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 23 x 37 x 9 x 452 x 1 x 991 = 75475646136
Therefore, the lowest common multiple of 814,414,904,253,991 is 75475646136.
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.
814 x 414 x 904 x 253 x 991 = 76381353889632
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
904 : 1, 2, 4, 8, 113, 226, 452, 904
253 : 1, 11, 23, 253
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,414,904,253,991, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
414:2x 3x 3x 23
904:2x 2x 2x 113
253:11x 23
991:991
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 11x 23 = 1012
Therefore, the value for common factors is 1012.
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 = 76381353889632/(1x1012)
LCM = 76381353889632/1012
LCM = 75475646136
Thus, we can understand that the LCM of 814,414,904,253,991 is 75475646136.
