Given numbers are 163,430,246,385,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 163,430,246,385,155 is 20578494090.
Find LCM of 163,430,246,385,155 with Prime Factorization
| 2 | 163, 430, 246, 385, 155 |
| 5 | 163, 215, 123, 385, 155 |
| 163, 43, 123, 77, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 163 x 43 x 123 x 77 x 31 = 20578494090
Therefore, the lowest common multiple of 163,430,246,385,155 is 20578494090.
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.
163 x 430 x 246 x 385 x 155 = 1028924704500
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.
163 : 1, 163
430 : 1, 2, 5, 10, 43, 86, 215, 430
246 : 1, 2, 3, 6, 41, 82, 123, 246
385 : 1, 5, 7, 11, 35, 55, 77, 385
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,430,246,385,155, is 1.
Now, the common factors can be found like this.
163:163
430:2x 5x 43
246:2x 3x 41
385:5x 7x 11
155:5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 1028924704500/(1x50)
LCM = 1028924704500/50
LCM = 20578494090
Thus, we can understand that the LCM of 163,430,246,385,155 is 20578494090.
