Given numbers are 896,756,987,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 896,756,987,961 is 1092680064.
Find LCM of 896,756,987,961 with Prime Factorization
| 2 | 896, 756, 987, 961 |
| 2 | 448, 378, 987, 961 |
| 3 | 224, 189, 987, 961 |
| 7 | 224, 63, 329, 961 |
| 32, 9, 47, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 32 x 9 x 47 x 961 = 1092680064
Therefore, the lowest common multiple of 896,756,987,961 is 1092680064.
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.
896 x 756 x 987 x 961 = 642495877632
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.
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
987 : 1, 3, 7, 21, 47, 141, 329, 987
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 896,756,987,961, is 1.
Now, the common factors can be found like this.
896:2x 2x 2x 2x 2x 2x 2x 7
756:2x 2x 3x 3x 3x 7
987:3x 7x 47
961:31x 31
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 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 642495877632/(1x588)
LCM = 642495877632/588
LCM = 1092680064
Thus, we can understand that the LCM of 896,756,987,961 is 1092680064.
