Given numbers are 235,223,231,686,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 235,223,231,686,715 is 15422477070.
Find LCM of 235,223,231,686,715 with Prime Factorization
| 5 | 235, 223, 231, 686, 715 |
| 7 | 47, 223, 231, 686, 143 |
| 11 | 47, 223, 33, 98, 143 |
| 47, 223, 3, 98, 13 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 47 x 223 x 3 x 98 x 13 = 15422477070
Therefore, the lowest common multiple of 235,223,231,686,715 is 15422477070.
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.
235 x 223 x 231 x 686 x 715 = 5937653671950
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.
235 : 1, 5, 47, 235
223 : 1, 223
231 : 1, 3, 7, 11, 21, 33, 77, 231
686 : 1, 2, 7, 14, 49, 98, 343, 686
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 235,223,231,686,715, is 1.
Now, the common factors can be found like this.
235:5x 47
223:223
231:3x 7x 11
686:2x 7x 7x 7
715:5x 11x 13
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 11 = 385
Therefore, the value for common factors is 385.
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 = 5937653671950/(1x385)
LCM = 5937653671950/385
LCM = 15422477070
Thus, we can understand that the LCM of 235,223,231,686,715 is 15422477070.
