Given numbers are 556,973,835,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,973,835,868 is 100744420.
Find LCM of 556,973,835,868 with Prime Factorization
| 2 | 556, 973, 835, 868 |
| 2 | 278, 973, 835, 434 |
| 7 | 139, 973, 835, 217 |
| 139 | 139, 139, 835, 31 |
| 1, 1, 835, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 139 x 1 x 1 x 835 x 31 = 100744420
Therefore, the lowest common multiple of 556,973,835,868 is 100744420.
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.
556 x 973 x 835 x 868 = 392097282640
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.
556 : 1, 2, 4, 139, 278, 556
973 : 1, 7, 139, 973
835 : 1, 5, 167, 835
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,973,835,868, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
973:7x 139
835:5x 167
868:2x 2x 7x 31
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 7x 139 = 3892
Therefore, the value for common factors is 3892.
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 = 392097282640/(1x3892)
LCM = 392097282640/3892
LCM = 100744420
Thus, we can understand that the LCM of 556,973,835,868 is 100744420.
