Given numbers are 794,488,180,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 794,488,180,765 is 148208040.
Find LCM of 794,488,180,765 with Prime Factorization
| 2 | 794, 488, 180, 765 |
| 2 | 397, 244, 90, 765 |
| 3 | 397, 122, 45, 765 |
| 3 | 397, 122, 15, 255 |
| 5 | 397, 122, 5, 85 |
| 397, 122, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 397 x 122 x 1 x 17 = 148208040
Therefore, the lowest common multiple of 794,488,180,765 is 148208040.
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.
794 x 488 x 180 x 765 = 53354894400
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.
794 : 1, 2, 397, 794
488 : 1, 2, 4, 8, 61, 122, 244, 488
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 794,488,180,765, is 1.
Now, the common factors can be found like this.
794:2x 397
488:2x 2x 2x 61
180:2x 2x 3x 3x 5
765:3x 3x 5x 17
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 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 53354894400/(1x360)
LCM = 53354894400/360
LCM = 148208040
Thus, we can understand that the LCM of 794,488,180,765 is 148208040.
