Given numbers are 741,921,418,136,706
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,921,418,136,706 is 120133154856.
Find LCM of 741,921,418,136,706 with Prime Factorization
| 2 | 741, 921, 418, 136, 706 |
| 3 | 741, 921, 209, 68, 353 |
| 19 | 247, 307, 209, 68, 353 |
| 13, 307, 11, 68, 353 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 13 x 307 x 11 x 68 x 353 = 120133154856
Therefore, the lowest common multiple of 741,921,418,136,706 is 120133154856.
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 921 x 418 x 136 x 706 = 27390359307168
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
921 : 1, 3, 307, 921
418 : 1, 2, 11, 19, 22, 38, 209, 418
136 : 1, 2, 4, 8, 17, 34, 68, 136
706 : 1, 2, 353, 706
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,921,418,136,706, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
921:3x 307
418:2x 11x 19
136:2x 2x 2x 17
706:2x 353
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 27390359307168/(1x228)
LCM = 27390359307168/228
LCM = 120133154856
Thus, we can understand that the LCM of 741,921,418,136,706 is 120133154856.
