Given numbers are 198,291,161,857,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,291,161,857,802 is 1062644491062.
Find LCM of 198,291,161,857,802 with Prime Factorization
| 2 | 198, 291, 161, 857, 802 |
| 3 | 99, 291, 161, 857, 401 |
| 33, 97, 161, 857, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 33 x 97 x 161 x 857 x 401 = 1062644491062
Therefore, the lowest common multiple of 198,291,161,857,802 is 1062644491062.
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.
198 x 291 x 161 x 857 x 802 = 6375866946372
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
291 : 1, 3, 97, 291
161 : 1, 7, 23, 161
857 : 1, 857
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,291,161,857,802, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
291:3x 97
161:7x 23
857:857
802:2x 401
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 6375866946372/(1x6)
LCM = 6375866946372/6
LCM = 1062644491062
Thus, we can understand that the LCM of 198,291,161,857,802 is 1062644491062.
