Given numbers are 982,942,381,822,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 982,942,381,822,817 is 6574742367126.
Find LCM of 982,942,381,822,817 with Prime Factorization
| 2 | 982, 942, 381, 822, 817 |
| 3 | 491, 471, 381, 411, 817 |
| 491, 157, 127, 137, 817 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 491 x 157 x 127 x 137 x 817 = 6574742367126
Therefore, the lowest common multiple of 982,942,381,822,817 is 6574742367126.
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.
982 x 942 x 381 x 822 x 817 = 236690725216536
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.
982 : 1, 2, 491, 982
942 : 1, 2, 3, 6, 157, 314, 471, 942
381 : 1, 3, 127, 381
822 : 1, 2, 3, 6, 137, 274, 411, 822
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 982,942,381,822,817, is 1.
Now, the common factors can be found like this.
982:2x 491
942:2x 3x 157
381:3x 127
822:2x 3x 137
817:19x 43
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 236690725216536/(1x36)
LCM = 236690725216536/36
LCM = 6574742367126
Thus, we can understand that the LCM of 982,942,381,822,817 is 6574742367126.
