Given numbers are 476,905,433,640,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 476,905,433,640,831 is 4960145662080.
Find LCM of 476,905,433,640,831 with Prime Factorization
| 2 | 476, 905, 433, 640, 831 |
| 2 | 238, 905, 433, 320, 831 |
| 5 | 119, 905, 433, 160, 831 |
| 119, 181, 433, 32, 831 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 119 x 181 x 433 x 32 x 831 = 4960145662080
Therefore, the lowest common multiple of 476,905,433,640,831 is 4960145662080.
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.
476 x 905 x 433 x 640 x 831 = 99202913241600
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
905 : 1, 5, 181, 905
433 : 1, 433
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,905,433,640,831, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
905:5x 181
433:433
640:2x 2x 2x 2x 2x 2x 2x 5
831:3x 277
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 5 = 20
Therefore, the value for common factors is 20.
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 = 99202913241600/(1x20)
LCM = 99202913241600/20
LCM = 4960145662080
Thus, we can understand that the LCM of 476,905,433,640,831 is 4960145662080.
