Given numbers are 991,310,155,633,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,310,155,633,155 is 194463930.
Find LCM of 991,310,155,633,155 with Prime Factorization
| 5 | 991, 310, 155, 633, 155 |
| 31 | 991, 62, 31, 633, 31 |
| 991, 2, 1, 633, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 31 x 991 x 2 x 1 x 633 x 1 = 194463930
Therefore, the lowest common multiple of 991,310,155,633,155 is 194463930.
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.
991 x 310 x 155 x 633 x 155 = 4671995918250
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.
991 : 1, 991
310 : 1, 2, 5, 10, 31, 62, 155, 310
155 : 1, 5, 31, 155
633 : 1, 3, 211, 633
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,310,155,633,155, is 1.
Now, the common factors can be found like this.
991:991
310:2x 5x 31
155:5x 31
633:3x 211
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.
5x 5x 31x 31 = 24025
Therefore, the value for common factors is 24025.
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 = 4671995918250/(1x24025)
LCM = 4671995918250/24025
LCM = 194463930
Thus, we can understand that the LCM of 991,310,155,633,155 is 194463930.
