Given numbers are 917,979,162,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,979,162,663 is 32140994886.
Find LCM of 917,979,162,663 with Prime Factorization
3 | 917, 979, 162, 663 |
917, 979, 54, 221 |
Multiply the prime numbers at the bottom and the left side.
3 x 917 x 979 x 54 x 221 = 32140994886
Therefore, the lowest common multiple of 917,979,162,663 is 32140994886.
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.
917 x 979 x 162 x 663 = 96422984658
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.
917 : 1, 7, 131, 917
979 : 1, 11, 89, 979
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,979,162,663, is 1.
Now, the common factors can be found like this.
917:7x 131
979:11x 89
162:2x 3x 3x 3x 3
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 96422984658/(1x3)
LCM = 96422984658/3
LCM = 32140994886
Thus, we can understand that the LCM of 917,979,162,663 is 32140994886.
