Given numbers are 293,361,121,220,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 293,361,121,220,961 is 245987804260.
Find LCM of 293,361,121,220,961 with Prime Factorization
| 11 | 293, 361, 121, 220, 961 |
| 293, 361, 11, 20, 961 |
Multiply the prime numbers at the bottom and the left side.
11 x 293 x 361 x 11 x 20 x 961 = 245987804260
Therefore, the lowest common multiple of 293,361,121,220,961 is 245987804260.
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.
293 x 361 x 121 x 220 x 961 = 2705865846860
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.
293 : 1, 293
361 : 1, 19, 361
121 : 1, 11, 121
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 293,361,121,220,961, is 1.
Now, the common factors can be found like this.
293:293
361:19x 19
121:11x 11
220:2x 2x 5x 11
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 2705865846860/(1x11)
LCM = 2705865846860/11
LCM = 245987804260
Thus, we can understand that the LCM of 293,361,121,220,961 is 245987804260.
