Given numbers are 991,442,978,168,703
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,442,978,168,703 is 4216170248472.
Find LCM of 991,442,978,168,703 with Prime Factorization
2 | 991, 442, 978, 168, 703 |
3 | 991, 221, 489, 84, 703 |
991, 221, 163, 28, 703 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 991 x 221 x 163 x 28 x 703 = 4216170248472
Therefore, the lowest common multiple of 991,442,978,168,703 is 4216170248472.
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 442 x 978 x 168 x 703 = 50594042981664
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
442 : 1, 2, 13, 17, 26, 34, 221, 442
978 : 1, 2, 3, 6, 163, 326, 489, 978
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,442,978,168,703, is 1.
Now, the common factors can be found like this.
991:991
442:2x 13x 17
978:2x 3x 163
168:2x 2x 2x 3x 7
703:19x 37
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 3 = 12
Therefore, the value for common factors is 12.
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 = 50594042981664/(1x12)
LCM = 50594042981664/12
LCM = 4216170248472
Thus, we can understand that the LCM of 991,442,978,168,703 is 4216170248472.
