Given numbers are 805,241,874,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,241,874,721 is 759335570.
Find LCM of 805,241,874,721 with Prime Factorization
| 7 | 805, 241, 874, 721 |
| 23 | 115, 241, 874, 103 |
| 5, 241, 38, 103 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 5 x 241 x 38 x 103 = 759335570
Therefore, the lowest common multiple of 805,241,874,721 is 759335570.
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.
805 x 241 x 874 x 721 = 122253026770
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
241 : 1, 241
874 : 1, 2, 19, 23, 38, 46, 437, 874
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,241,874,721, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
241:241
874:2x 19x 23
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 122253026770/(1x161)
LCM = 122253026770/161
LCM = 759335570
Thus, we can understand that the LCM of 805,241,874,721 is 759335570.
