Given numbers are 561,782,730,734,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,782,730,734,762 is 439019026710.
Find LCM of 561,782,730,734,762 with Prime Factorization
| 2 | 561, 782, 730, 734, 762 |
| 3 | 561, 391, 365, 367, 381 |
| 17 | 187, 391, 365, 367, 127 |
| 11, 23, 365, 367, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 11 x 23 x 365 x 367 x 127 = 439019026710
Therefore, the lowest common multiple of 561,782,730,734,762 is 439019026710.
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.
561 x 782 x 730 x 734 x 762 = 179119762897680
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
782 : 1, 2, 17, 23, 34, 46, 391, 782
730 : 1, 2, 5, 10, 73, 146, 365, 730
734 : 1, 2, 367, 734
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,782,730,734,762, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
782:2x 17x 23
730:2x 5x 73
734:2x 367
762:2x 3x 127
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 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 179119762897680/(1x408)
LCM = 179119762897680/408
LCM = 439019026710
Thus, we can understand that the LCM of 561,782,730,734,762 is 439019026710.
