Given numbers are 741,867,919,642,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,867,919,642,923 is 2990223733614.
Find LCM of 741,867,919,642,923 with Prime Factorization
| 3 | 741, 867, 919, 642, 923 |
| 13 | 247, 289, 919, 214, 923 |
| 19, 289, 919, 214, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 19 x 289 x 919 x 214 x 71 = 2990223733614
Therefore, the lowest common multiple of 741,867,919,642,923 is 2990223733614.
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.
741 x 867 x 919 x 642 x 923 = 349856176832838
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
867 : 1, 3, 17, 51, 289, 867
919 : 1, 919
642 : 1, 2, 3, 6, 107, 214, 321, 642
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,867,919,642,923, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
867:3x 17x 17
919:919
642:2x 3x 107
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 349856176832838/(1x117)
LCM = 349856176832838/117
LCM = 2990223733614
Thus, we can understand that the LCM of 741,867,919,642,923 is 2990223733614.
