Given numbers are 556,726,506,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,726,506,644 is 32494308.
Find LCM of 556,726,506,644 with Prime Factorization
| 2 | 556, 726, 506, 644 |
| 2 | 278, 363, 253, 322 |
| 11 | 139, 363, 253, 161 |
| 23 | 139, 33, 23, 161 |
| 139, 33, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 23 x 139 x 33 x 1 x 7 = 32494308
Therefore, the lowest common multiple of 556,726,506,644 is 32494308.
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 726 x 506 x 644 = 131536958784
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
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
506 : 1, 2, 11, 22, 23, 46, 253, 506
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,726,506,644, is 2.
Now, the common factors can be found like this.
556:2x 2x 139
726:2x 3x 11x 11
506:2x 11x 23
644:2x 2x 7x 23
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 11x 23 = 2024
Therefore, the value for common factors is 2024.
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 = 131536958784/(2x2024)
LCM = 131536958784/4048
LCM = 32494308
Thus, we can understand that the LCM of 556,726,506,644 is 32494308.
