Given numbers are 195,831,690,385,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 195,831,690,385,894 is 28506848370.
Find LCM of 195,831,690,385,894 with Prime Factorization
| 2 | 195, 831, 690, 385, 894 |
| 3 | 195, 831, 345, 385, 447 |
| 5 | 65, 277, 115, 385, 149 |
| 13, 277, 23, 77, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 277 x 23 x 77 x 149 = 28506848370
Therefore, the lowest common multiple of 195,831,690,385,894 is 28506848370.
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.
195 x 831 x 690 x 385 x 894 = 38484245299500
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.
195 : 1, 3, 5, 13, 15, 39, 65, 195
831 : 1, 3, 277, 831
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
385 : 1, 5, 7, 11, 35, 55, 77, 385
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 195,831,690,385,894, is 1.
Now, the common factors can be found like this.
195:3x 5x 13
831:3x 277
690:2x 3x 5x 23
385:5x 7x 11
894:2x 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 3x 3x 3x 5x 5 = 1350
Therefore, the value for common factors is 1350.
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 = 38484245299500/(1x1350)
LCM = 38484245299500/1350
LCM = 28506848370
Thus, we can understand that the LCM of 195,831,690,385,894 is 28506848370.
