Given numbers are 131,970,388,802,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,970,388,802,217 is 22114500380.
Find LCM of 131,970,388,802,217 with Prime Factorization
| 2 | 131, 970, 388, 802, 217 |
| 97 | 131, 485, 194, 401, 217 |
| 131, 5, 2, 401, 217 |
Multiply the prime numbers at the bottom and the left side.
2 x 97 x 131 x 5 x 2 x 401 x 217 = 22114500380
Therefore, the lowest common multiple of 131,970,388,802,217 is 22114500380.
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.
131 x 970 x 388 x 802 x 217 = 8580426147440
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.
131 : 1, 131
970 : 1, 2, 5, 10, 97, 194, 485, 970
388 : 1, 2, 4, 97, 194, 388
802 : 1, 2, 401, 802
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,970,388,802,217, is 1.
Now, the common factors can be found like this.
131:131
970:2x 5x 97
388:2x 2x 97
802:2x 401
217:7x 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 2x 97 = 388
Therefore, the value for common factors is 388.
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 = 8580426147440/(1x388)
LCM = 8580426147440/388
LCM = 22114500380
Thus, we can understand that the LCM of 131,970,388,802,217 is 22114500380.
