Given numbers are 706,558,840,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 706,558,840,120 is 27576360.
Find LCM of 706,558,840,120 with Prime Factorization
| 2 | 706, 558, 840, 120 |
| 2 | 353, 279, 420, 60 |
| 2 | 353, 279, 210, 30 |
| 3 | 353, 279, 105, 15 |
| 5 | 353, 93, 35, 5 |
| 353, 93, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 353 x 93 x 7 x 1 = 27576360
Therefore, the lowest common multiple of 706,558,840,120 is 27576360.
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.
706 x 558 x 840 x 120 = 39709958400
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.
706 : 1, 2, 353, 706
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,558,840,120, is 2.
Now, the common factors can be found like this.
706:2x 353
558:2x 3x 3x 31
840:2x 2x 2x 3x 5x 7
120:2x 2x 2x 3x 5
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 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 39709958400/(2x720)
LCM = 39709958400/1440
LCM = 27576360
Thus, we can understand that the LCM of 706,558,840,120 is 27576360.
