Given numbers are 741,195,153,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,195,153,441 is 9258795.
Find LCM of 741,195,153,441 with Prime Factorization
| 3 | 741, 195, 153, 441 |
| 3 | 247, 65, 51, 147 |
| 13 | 247, 65, 17, 49 |
| 19, 5, 17, 49 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 19 x 5 x 17 x 49 = 9258795
Therefore, the lowest common multiple of 741,195,153,441 is 9258795.
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 195 x 153 x 441 = 9749511135
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
195 : 1, 3, 5, 13, 15, 39, 65, 195
153 : 1, 3, 9, 17, 51, 153
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,195,153,441, is 3.
Now, the common factors can be found like this.
741:3x 13x 19
195:3x 5x 13
153:3x 3x 17
441:3x 3x 7x 7
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 3x 13 = 351
Therefore, the value for common factors is 351.
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 = 9749511135/(3x351)
LCM = 9749511135/1053
LCM = 9258795
Thus, we can understand that the LCM of 741,195,153,441 is 9258795.
