Given numbers are 875,299,455,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 875,299,455,861 is 32179875.
Find LCM of 875,299,455,861 with Prime Factorization
| 5 | 875, 299, 455, 861 |
| 7 | 175, 299, 91, 861 |
| 13 | 25, 299, 13, 123 |
| 25, 23, 1, 123 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 13 x 25 x 23 x 1 x 123 = 32179875
Therefore, the lowest common multiple of 875,299,455,861 is 32179875.
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.
875 x 299 x 455 x 861 = 102492901875
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.
875 : 1, 5, 7, 25, 35, 125, 175, 875
299 : 1, 13, 23, 299
455 : 1, 5, 7, 13, 35, 65, 91, 455
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 875,299,455,861, is 1.
Now, the common factors can be found like this.
875:5x 5x 5x 7
299:13x 23
455:5x 7x 13
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 7x 13 = 3185
Therefore, the value for common factors is 3185.
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 = 102492901875/(1x3185)
LCM = 102492901875/3185
LCM = 32179875
Thus, we can understand that the LCM of 875,299,455,861 is 32179875.
