Given numbers are 958,891,640,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 958,891,640,102 is 4643464320.
Find LCM of 958,891,640,102 with Prime Factorization
| 2 | 958, 891, 640, 102 |
| 3 | 479, 891, 320, 51 |
| 479, 297, 320, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 479 x 297 x 320 x 17 = 4643464320
Therefore, the lowest common multiple of 958,891,640,102 is 4643464320.
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.
958 x 891 x 640 x 102 = 55721571840
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.
958 : 1, 2, 479, 958
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 958,891,640,102, is 1.
Now, the common factors can be found like this.
958:2x 479
891:3x 3x 3x 3x 11
640:2x 2x 2x 2x 2x 2x 2x 5
102:2x 3x 17
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 3 = 12
Therefore, the value for common factors is 12.
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 = 55721571840/(1x12)
LCM = 55721571840/12
LCM = 4643464320
Thus, we can understand that the LCM of 958,891,640,102 is 4643464320.
