Given numbers are 721,841,678,317,741
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,841,678,317,741 is 32189717838642.
Find LCM of 721,841,678,317,741 with Prime Factorization
3 | 721, 841, 678, 317, 741 |
721, 841, 226, 317, 247 |
Multiply the prime numbers at the bottom and the left side.
3 x 721 x 841 x 226 x 317 x 247 = 32189717838642
Therefore, the lowest common multiple of 721,841,678,317,741 is 32189717838642.
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.
721 x 841 x 678 x 317 x 741 = 96569153515926
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.
721 : 1, 7, 103, 721
841 : 1, 29, 841
678 : 1, 2, 3, 6, 113, 226, 339, 678
317 : 1, 317
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,841,678,317,741, is 1.
Now, the common factors can be found like this.
721:7x 103
841:29x 29
678:2x 3x 113
317:317
741:3x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 96569153515926/(1x3)
LCM = 96569153515926/3
LCM = 32189717838642
Thus, we can understand that the LCM of 721,841,678,317,741 is 32189717838642.
