Given numbers are 381,254,893,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,254,893,161 is 109555026.
Find LCM of 381,254,893,161 with Prime Factorization
| 127 | 381, 254, 893, 161 |
| 3, 2, 893, 161 |
Multiply the prime numbers at the bottom and the left side.
127 x 3 x 2 x 893 x 161 = 109555026
Therefore, the lowest common multiple of 381,254,893,161 is 109555026.
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.
381 x 254 x 893 x 161 = 13913488302
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.
381 : 1, 3, 127, 381
254 : 1, 2, 127, 254
893 : 1, 19, 47, 893
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,254,893,161, is 1.
Now, the common factors can be found like this.
381:3x 127
254:2x 127
893:19x 47
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
127 = 127
Therefore, the value for common factors is 127.
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 = 13913488302/(1x127)
LCM = 13913488302/127
LCM = 109555026
Thus, we can understand that the LCM of 381,254,893,161 is 109555026.
