Given numbers are 668,334,120,205
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,334,120,205 is 821640.
Find LCM of 668,334,120,205 with Prime Factorization
2 | 668, 334, 120, 205 |
2 | 334, 167, 60, 205 |
5 | 167, 167, 30, 205 |
167 | 167, 167, 6, 41 |
1, 1, 6, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 167 x 1 x 1 x 6 x 41 = 821640
Therefore, the lowest common multiple of 668,334,120,205 is 821640.
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.
668 x 334 x 120 x 205 = 5488555200
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.
668 : 1, 2, 4, 167, 334, 668
334 : 1, 2, 167, 334
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
205 : 1, 5, 41, 205
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,334,120,205, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
334:2x 167
120:2x 2x 2x 3x 5
205:5x 41
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 5x 167 = 6680
Therefore, the value for common factors is 6680.
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 = 5488555200/(1x6680)
LCM = 5488555200/6680
LCM = 821640
Thus, we can understand that the LCM of 668,334,120,205 is 821640.
