Given numbers are 481,343,476,922,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,343,476,922,918 is 139640951268.
Find LCM of 481,343,476,922,918 with Prime Factorization
| 2 | 481, 343, 476, 922, 918 |
| 7 | 481, 343, 238, 461, 459 |
| 17 | 481, 49, 34, 461, 459 |
| 481, 49, 2, 461, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 481 x 49 x 2 x 461 x 27 = 139640951268
Therefore, the lowest common multiple of 481,343,476,922,918 is 139640951268.
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.
481 x 343 x 476 x 922 x 918 = 66469092803568
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.
481 : 1, 13, 37, 481
343 : 1, 7, 49, 343
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
922 : 1, 2, 461, 922
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,343,476,922,918, is 1.
Now, the common factors can be found like this.
481:13x 37
343:7x 7x 7
476:2x 2x 7x 17
922:2x 461
918:2x 3x 3x 3x 17
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 7x 17 = 476
Therefore, the value for common factors is 476.
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 = 66469092803568/(1x476)
LCM = 66469092803568/476
LCM = 139640951268
Thus, we can understand that the LCM of 481,343,476,922,918 is 139640951268.
