Given numbers are 865,198,451,286,677
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,198,451,286,677 is 61801238070.
Find LCM of 865,198,451,286,677 with Prime Factorization
| 2 | 865, 198, 451, 286, 677 |
| 11 | 865, 99, 451, 143, 677 |
| 865, 9, 41, 13, 677 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 865 x 9 x 41 x 13 x 677 = 61801238070
Therefore, the lowest common multiple of 865,198,451,286,677 is 61801238070.
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.
865 x 198 x 451 x 286 x 677 = 14955899612940
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.
865 : 1, 5, 173, 865
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
451 : 1, 11, 41, 451
286 : 1, 2, 11, 13, 22, 26, 143, 286
677 : 1, 677
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,198,451,286,677, is 1.
Now, the common factors can be found like this.
865:5x 173
198:2x 3x 3x 11
451:11x 41
286:2x 11x 13
677:677
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 14955899612940/(1x242)
LCM = 14955899612940/242
LCM = 61801238070
Thus, we can understand that the LCM of 865,198,451,286,677 is 61801238070.
