Given numbers are 960,901,861,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 960,901,861,505 is 25072595520.
Find LCM of 960,901,861,505 with Prime Factorization
| 3 | 960, 901, 861, 505 |
| 5 | 320, 901, 287, 505 |
| 64, 901, 287, 101 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 64 x 901 x 287 x 101 = 25072595520
Therefore, the lowest common multiple of 960,901,861,505 is 25072595520.
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.
960 x 901 x 861 x 505 = 376088932800
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.
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
901 : 1, 17, 53, 901
861 : 1, 3, 7, 21, 41, 123, 287, 861
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 960,901,861,505, is 1.
Now, the common factors can be found like this.
960:2x 2x 2x 2x 2x 2x 3x 5
901:17x 53
861:3x 7x 41
505:5x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 376088932800/(1x15)
LCM = 376088932800/15
LCM = 25072595520
Thus, we can understand that the LCM of 960,901,861,505 is 25072595520.
