Given numbers are 987,934,640,957,159
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,934,640,957,159 is 4987473025920.
Find LCM of 987,934,640,957,159 with Prime Factorization
| 2 | 987, 934, 640, 957, 159 |
| 3 | 987, 467, 320, 957, 159 |
| 329, 467, 320, 319, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 329 x 467 x 320 x 319 x 53 = 4987473025920
Therefore, the lowest common multiple of 987,934,640,957,159 is 4987473025920.
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.
987 x 934 x 640 x 957 x 159 = 89774514466560
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
934 : 1, 2, 467, 934
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
957 : 1, 3, 11, 29, 33, 87, 319, 957
159 : 1, 3, 53, 159
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,934,640,957,159, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
934:2x 467
640:2x 2x 2x 2x 2x 2x 2x 5
957:3x 11x 29
159:3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 89774514466560/(1x18)
LCM = 89774514466560/18
LCM = 4987473025920
Thus, we can understand that the LCM of 987,934,640,957,159 is 4987473025920.
