Given numbers are 143,121,392,455,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 143,121,392,455,705 is 434714280.
Find LCM of 143,121,392,455,705 with Prime Factorization
| 5 | 143, 121, 392, 455, 705 |
| 7 | 143, 121, 392, 91, 141 |
| 11 | 143, 121, 56, 13, 141 |
| 13 | 13, 11, 56, 13, 141 |
| 1, 11, 56, 1, 141 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 13 x 1 x 11 x 56 x 1 x 141 = 434714280
Therefore, the lowest common multiple of 143,121,392,455,705 is 434714280.
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.
143 x 121 x 392 x 455 x 705 = 2175744971400
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.
143 : 1, 11, 13, 143
121 : 1, 11, 121
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
455 : 1, 5, 7, 13, 35, 65, 91, 455
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,121,392,455,705, is 1.
Now, the common factors can be found like this.
143:11x 13
121:11x 11
392:2x 2x 2x 7x 7
455:5x 7x 13
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 11x 13 = 5005
Therefore, the value for common factors is 5005.
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 = 2175744971400/(1x5005)
LCM = 2175744971400/5005
LCM = 434714280
Thus, we can understand that the LCM of 143,121,392,455,705 is 434714280.
