Given numbers are 959,112,706,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 959,112,706,420 is 81246480.
Find LCM of 959,112,706,420 with Prime Factorization
| 2 | 959, 112, 706, 420 |
| 2 | 959, 56, 353, 210 |
| 7 | 959, 28, 353, 105 |
| 137, 4, 353, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 137 x 4 x 353 x 15 = 81246480
Therefore, the lowest common multiple of 959,112,706,420 is 81246480.
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.
959 x 112 x 706 x 420 = 31848620160
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.
959 : 1, 7, 137, 959
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
706 : 1, 2, 353, 706
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 959,112,706,420, is 1.
Now, the common factors can be found like this.
959:7x 137
112:2x 2x 2x 2x 7
706:2x 353
420:2x 2x 3x 5x 7
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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 31848620160/(1x392)
LCM = 31848620160/392
LCM = 81246480
Thus, we can understand that the LCM of 959,112,706,420 is 81246480.
