Given numbers are 989,987,358,616,895
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,987,358,616,895 is 76881022680.
Find LCM of 989,987,358,616,895 with Prime Factorization
| 2 | 989, 987, 358, 616, 895 |
| 7 | 989, 987, 179, 308, 895 |
| 179 | 989, 141, 179, 44, 895 |
| 989, 141, 1, 44, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 179 x 989 x 141 x 1 x 44 x 5 = 76881022680
Therefore, the lowest common multiple of 989,987,358,616,895 is 76881022680.
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.
989 x 987 x 358 x 616 x 895 = 192663842836080
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.
989 : 1, 23, 43, 989
987 : 1, 3, 7, 21, 47, 141, 329, 987
358 : 1, 2, 179, 358
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
895 : 1, 5, 179, 895
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,987,358,616,895, is 1.
Now, the common factors can be found like this.
989:23x 43
987:3x 7x 47
358:2x 179
616:2x 2x 2x 7x 11
895:5x 179
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 179 = 2506
Therefore, the value for common factors is 2506.
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 = 192663842836080/(1x2506)
LCM = 192663842836080/2506
LCM = 76881022680
Thus, we can understand that the LCM of 989,987,358,616,895 is 76881022680.
