Given numbers are 869,616,799,322,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,616,799,322,455 is 58129391320.
Find LCM of 869,616,799,322,455 with Prime Factorization
| 2 | 869, 616, 799, 322, 455 |
| 7 | 869, 308, 799, 161, 455 |
| 11 | 869, 44, 799, 23, 65 |
| 79, 4, 799, 23, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 79 x 4 x 799 x 23 x 65 = 58129391320
Therefore, the lowest common multiple of 869,616,799,322,455 is 58129391320.
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.
869 x 616 x 799 x 322 x 455 = 62663483842960
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.
869 : 1, 11, 79, 869
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
799 : 1, 17, 47, 799
322 : 1, 2, 7, 14, 23, 46, 161, 322
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,616,799,322,455, is 1.
Now, the common factors can be found like this.
869:11x 79
616:2x 2x 2x 7x 11
799:17x 47
322:2x 7x 23
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 11 = 1078
Therefore, the value for common factors is 1078.
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 = 62663483842960/(1x1078)
LCM = 62663483842960/1078
LCM = 58129391320
Thus, we can understand that the LCM of 869,616,799,322,455 is 58129391320.
