Given numbers are 991,985,964,850,872
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,985,964,850,872 is 17436621414200.
Find LCM of 991,985,964,850,872 with Prime Factorization
| 2 | 991, 985, 964, 850, 872 |
| 2 | 991, 985, 482, 425, 436 |
| 5 | 991, 985, 241, 425, 218 |
| 991, 197, 241, 85, 218 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 991 x 197 x 241 x 85 x 218 = 17436621414200
Therefore, the lowest common multiple of 991,985,964,850,872 is 17436621414200.
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 985 x 964 x 850 x 872 = 697464856568000
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
985 : 1, 5, 197, 985
964 : 1, 2, 4, 241, 482, 964
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,985,964,850,872, is 1.
Now, the common factors can be found like this.
991:991
985:5x 197
964:2x 2x 241
850:2x 5x 5x 17
872:2x 2x 2x 109
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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 697464856568000/(1x40)
LCM = 697464856568000/40
LCM = 17436621414200
Thus, we can understand that the LCM of 991,985,964,850,872 is 17436621414200.
