Given numbers are 115,680,713,421,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,680,713,421,831 is 169621758840.
Find LCM of 115,680,713,421,831 with Prime Factorization
| 5 | 115, 680, 713, 421, 831 |
| 23 | 23, 136, 713, 421, 831 |
| 1, 136, 31, 421, 831 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 1 x 136 x 31 x 421 x 831 = 169621758840
Therefore, the lowest common multiple of 115,680,713,421,831 is 169621758840.
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.
115 x 680 x 713 x 421 x 831 = 19506502266600
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.
115 : 1, 5, 23, 115
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
713 : 1, 23, 31, 713
421 : 1, 421
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,680,713,421,831, is 1.
Now, the common factors can be found like this.
115:5x 23
680:2x 2x 2x 5x 17
713:23x 31
421:421
831:3x 277
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23 = 115
Therefore, the value for common factors is 115.
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 = 19506502266600/(1x115)
LCM = 19506502266600/115
LCM = 169621758840
Thus, we can understand that the LCM of 115,680,713,421,831 is 169621758840.
