Given numbers are 895,820,988,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 895,820,988,646 is 616329220.
Find LCM of 895,820,988,646 with Prime Factorization
| 2 | 895, 820, 988, 646 |
| 2 | 895, 410, 494, 323 |
| 5 | 895, 205, 247, 323 |
| 19 | 179, 41, 247, 323 |
| 179, 41, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 179 x 41 x 13 x 17 = 616329220
Therefore, the lowest common multiple of 895,820,988,646 is 616329220.
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.
895 x 820 x 988 x 646 = 468410207200
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.
895 : 1, 5, 179, 895
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 895,820,988,646, is 1.
Now, the common factors can be found like this.
895:5x 179
820:2x 2x 5x 41
988:2x 2x 13x 19
646:2x 17x 19
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 5x 19 = 760
Therefore, the value for common factors is 760.
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 = 468410207200/(1x760)
LCM = 468410207200/760
LCM = 616329220
Thus, we can understand that the LCM of 895,820,988,646 is 616329220.
