Find LCM of 795,195,668,720 with Prime Factorization
| 2 | 795, 195, 668, 720 |
| 2 | 795, 195, 334, 360 |
| 3 | 795, 195, 167, 180 |
| 5 | 265, 65, 167, 60 |
| 53, 13, 167, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 53 x 13 x 167 x 12 = 82845360
Therefore, the lowest common multiple of 795,195,668,720 is 82845360.
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.
795 x 195 x 668 x 720 = 74560824000
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.
795 : 1, 3, 5, 15, 53, 159, 265, 795
195 : 1, 3, 5, 13, 15, 39, 65, 195
668 : 1, 2, 4, 167, 334, 668
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 795,195,668,720, is 1.
Now, the common factors can be found like this.
795:3x 5x 53
195:3x 5x 13
668:2x 2x 167
720:2x 2x 2x 2x 3x 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 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 74560824000/(1x900)
LCM = 74560824000/900
LCM = 82845360
Thus, we can understand that the LCM of 795,195,668,720 is 82845360.
