Given numbers are 580,895,690,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 580,895,690,720 is 85962960.
Find LCM of 580,895,690,720 with Prime Factorization
| 2 | 580, 895, 690, 720 |
| 2 | 290, 895, 345, 360 |
| 3 | 145, 895, 345, 180 |
| 5 | 145, 895, 115, 60 |
| 29, 179, 23, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 29 x 179 x 23 x 12 = 85962960
Therefore, the lowest common multiple of 580,895,690,720 is 85962960.
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.
580 x 895 x 690 x 720 = 257888880000
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.
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
895 : 1, 5, 179, 895
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
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
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 580,895,690,720, is 5.
Now, the common factors can be found like this.
580:2x 2x 5x 29
895:5x 179
690:2x 3x 5x 23
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 2x 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 257888880000/(5x600)
LCM = 257888880000/3000
LCM = 85962960
Thus, we can understand that the LCM of 580,895,690,720 is 85962960.
