Given numbers are 991,771,940,481,496
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,771,940,481,496 is 42837355026960.
Find LCM of 991,771,940,481,496 with Prime Factorization
| 2 | 991, 771, 940, 481, 496 |
| 2 | 991, 771, 470, 481, 248 |
| 991, 771, 235, 481, 124 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 991 x 771 x 235 x 481 x 124 = 42837355026960
Therefore, the lowest common multiple of 991,771,940,481,496 is 42837355026960.
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.
991 x 771 x 940 x 481 x 496 = 171349420107840
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.
991 : 1, 991
771 : 1, 3, 257, 771
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
481 : 1, 13, 37, 481
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,771,940,481,496, is 1.
Now, the common factors can be found like this.
991:991
771:3x 257
940:2x 2x 5x 47
481:13x 37
496:2x 2x 2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 171349420107840/(1x4)
LCM = 171349420107840/4
LCM = 42837355026960
Thus, we can understand that the LCM of 991,771,940,481,496 is 42837355026960.
