Given numbers are 481,221,646,703
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,221,646,703 is 310726.
Find LCM of 481,221,646,703 with Prime Factorization
13 | 481, 221, 646, 703 |
17 | 37, 17, 646, 703 |
19 | 37, 1, 38, 703 |
37 | 37, 1, 2, 37 |
1, 1, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 19 x 37 x 1 x 1 x 2 x 1 = 310726
Therefore, the lowest common multiple of 481,221,646,703 is 310726.
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 221 x 646 x 703 = 48275323538
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
221 : 1, 13, 17, 221
646 : 1, 2, 17, 19, 34, 38, 323, 646
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,221,646,703, is 1.
Now, the common factors can be found like this.
481:13x 37
221:13x 17
646:2x 17x 19
703:19x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17x 19x 37 = 155363
Therefore, the value for common factors is 155363.
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 = 48275323538/(1x155363)
LCM = 48275323538/155363
LCM = 310726
Thus, we can understand that the LCM of 481,221,646,703 is 310726.
