Given numbers are 561,628,650
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,628,650 is 114500100.
Find LCM of 561,628,650 with Prime Factorization
| 2 | 561, 628, 650 |
| 561, 314, 325 |
Multiply the prime numbers at the bottom and the left side.
2 x 561 x 314 x 325 = 114500100
Therefore, the lowest common multiple of 561,628,650 is 114500100.
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 628 x 650 = 229000200
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
628 : 1, 2, 4, 157, 314, 628
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,628,650, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
628:2x 2x 157
650:2x 5x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 229000200/(1x2)
LCM = 229000200/2
LCM = 114500100
Thus, we can understand that the LCM of 561,628,650 is 114500100.
