Given numbers are 481,361,513,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,361,513,969 is 79701219.
Find LCM of 481,361,513,969 with Prime Factorization
| 3 | 481, 361, 513, 969 |
| 19 | 481, 361, 171, 323 |
| 481, 19, 9, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 481 x 19 x 9 x 17 = 79701219
Therefore, the lowest common multiple of 481,361,513,969 is 79701219.
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 361 x 513 x 969 = 86316420177
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
361 : 1, 19, 361
513 : 1, 3, 9, 19, 27, 57, 171, 513
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,361,513,969, is 1.
Now, the common factors can be found like this.
481:13x 37
361:19x 19
513:3x 3x 3x 19
969:3x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19x 19 = 1083
Therefore, the value for common factors is 1083.
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 = 86316420177/(1x1083)
LCM = 86316420177/1083
LCM = 79701219
Thus, we can understand that the LCM of 481,361,513,969 is 79701219.
