Given numbers are 327,840,126,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 327,840,126,655 is 35983080.
Find LCM of 327,840,126,655 with Prime Factorization
2 | 327, 840, 126, 655 |
3 | 327, 420, 63, 655 |
5 | 109, 140, 21, 655 |
7 | 109, 28, 21, 131 |
109, 4, 3, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 109 x 4 x 3 x 131 = 35983080
Therefore, the lowest common multiple of 327,840,126,655 is 35983080.
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.
327 x 840 x 126 x 655 = 22669340400
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.
327 : 1, 3, 109, 327
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
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 327,840,126,655, is 1.
Now, the common factors can be found like this.
327:3x 109
840:2x 2x 2x 3x 5x 7
126:2x 3x 3x 7
655:5x 131
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 3x 5x 7 = 630
Therefore, the value for common factors is 630.
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 = 22669340400/(1x630)
LCM = 22669340400/630
LCM = 35983080
Thus, we can understand that the LCM of 327,840,126,655 is 35983080.
