Given numbers are 121,142,348,736,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 121,142,348,736,447 is 81964737888.
Find LCM of 121,142,348,736,447 with Prime Factorization
| 2 | 121, 142, 348, 736, 447 |
| 2 | 121, 71, 174, 368, 447 |
| 3 | 121, 71, 87, 184, 447 |
| 121, 71, 29, 184, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 121 x 71 x 29 x 184 x 149 = 81964737888
Therefore, the lowest common multiple of 121,142,348,736,447 is 81964737888.
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.
121 x 142 x 348 x 736 x 447 = 1967153709312
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.
121 : 1, 11, 121
142 : 1, 2, 71, 142
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,142,348,736,447, is 1.
Now, the common factors can be found like this.
121:11x 11
142:2x 71
348:2x 2x 3x 29
736:2x 2x 2x 2x 2x 23
447:3x 149
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 1967153709312/(1x24)
LCM = 1967153709312/24
LCM = 81964737888
Thus, we can understand that the LCM of 121,142,348,736,447 is 81964737888.
