Given numbers are 998,417,788,956,268
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,417,788,956,268 is 2625642066252.
Find LCM of 998,417,788,956,268 with Prime Factorization
| 2 | 998, 417, 788, 956, 268 |
| 2 | 499, 417, 394, 478, 134 |
| 499, 417, 197, 239, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 499 x 417 x 197 x 239 x 67 = 2625642066252
Therefore, the lowest common multiple of 998,417,788,956,268 is 2625642066252.
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.
998 x 417 x 788 x 956 x 268 = 84020546120064
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.
998 : 1, 2, 499, 998
417 : 1, 3, 139, 417
788 : 1, 2, 4, 197, 394, 788
956 : 1, 2, 4, 239, 478, 956
268 : 1, 2, 4, 67, 134, 268
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,417,788,956,268, is 1.
Now, the common factors can be found like this.
998:2x 499
417:3x 139
788:2x 2x 197
956:2x 2x 239
268:2x 2x 67
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 2 = 32
Therefore, the value for common factors is 32.
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 = 84020546120064/(1x32)
LCM = 84020546120064/32
LCM = 2625642066252
Thus, we can understand that the LCM of 998,417,788,956,268 is 2625642066252.
