Given numbers are 991,961,169,774,912
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,961,169,774,912 is 18935130185712.
Find LCM of 991,961,169,774,912 with Prime Factorization
2 | 991, 961, 169, 774, 912 |
3 | 991, 961, 169, 387, 456 |
991, 961, 169, 129, 152 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 991 x 961 x 169 x 129 x 152 = 18935130185712
Therefore, the lowest common multiple of 991,961,169,774,912 is 18935130185712.
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 961 x 169 x 774 x 912 = 113610781114272
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
961 : 1, 31, 961
169 : 1, 13, 169
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,961,169,774,912, is 1.
Now, the common factors can be found like this.
991:991
961:31x 31
169:13x 13
774:2x 3x 3x 43
912:2x 2x 2x 2x 3x 19
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 = 113610781114272/(1x6)
LCM = 113610781114272/6
LCM = 18935130185712
Thus, we can understand that the LCM of 991,961,169,774,912 is 18935130185712.
