Given numbers are 155,699,845,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,699,845,897 is 421137015.
Find LCM of 155,699,845,897 with Prime Factorization
| 3 | 155, 699, 845, 897 |
| 5 | 155, 233, 845, 299 |
| 13 | 31, 233, 169, 299 |
| 31, 233, 13, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 31 x 233 x 13 x 23 = 421137015
Therefore, the lowest common multiple of 155,699,845,897 is 421137015.
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.
155 x 699 x 845 x 897 = 82121717925
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.
155 : 1, 5, 31, 155
699 : 1, 3, 233, 699
845 : 1, 5, 13, 65, 169, 845
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,699,845,897, is 1.
Now, the common factors can be found like this.
155:5x 31
699:3x 233
845:5x 13x 13
897:3x 13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13 = 195
Therefore, the value for common factors is 195.
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 = 82121717925/(1x195)
LCM = 82121717925/195
LCM = 421137015
Thus, we can understand that the LCM of 155,699,845,897 is 421137015.
