Given numbers are 835,638,151,840,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 835,638,151,840,655 is 885186298920.
Find LCM of 835,638,151,840,655 with Prime Factorization
| 2 | 835, 638, 151, 840, 655 |
| 5 | 835, 319, 151, 420, 655 |
| 167, 319, 151, 84, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 167 x 319 x 151 x 84 x 131 = 885186298920
Therefore, the lowest common multiple of 835,638,151,840,655 is 885186298920.
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.
835 x 638 x 151 x 840 x 655 = 44259314946000
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.
835 : 1, 5, 167, 835
638 : 1, 2, 11, 22, 29, 58, 319, 638
151 : 1, 151
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
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 835,638,151,840,655, is 1.
Now, the common factors can be found like this.
835:5x 167
638:2x 11x 29
151:151
840:2x 2x 2x 3x 5x 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 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 44259314946000/(1x50)
LCM = 44259314946000/50
LCM = 885186298920
Thus, we can understand that the LCM of 835,638,151,840,655 is 885186298920.
