Given numbers are 561,846,631,150,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,846,631,150,120 is 9982546200.
Find LCM of 561,846,631,150,120 with Prime Factorization
| 2 | 561, 846, 631, 150, 120 |
| 3 | 561, 423, 631, 75, 60 |
| 5 | 187, 141, 631, 25, 20 |
| 187, 141, 631, 5, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 187 x 141 x 631 x 5 x 4 = 9982546200
Therefore, the lowest common multiple of 561,846,631,150,120 is 9982546200.
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 846 x 631 x 150 x 120 = 5390574948000
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
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
631 : 1, 631
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,846,631,150,120, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
846:2x 3x 3x 47
631:631
150:2x 3x 5x 5
120:2x 2x 2x 3x 5
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 3x 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 5390574948000/(1x540)
LCM = 5390574948000/540
LCM = 9982546200
Thus, we can understand that the LCM of 561,846,631,150,120 is 9982546200.
