Given numbers are 854,716,488,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 854,716,488,556 is 84993496.
Find LCM of 854,716,488,556 with Prime Factorization
| 2 | 854, 716, 488, 556 |
| 2 | 427, 358, 244, 278 |
| 61 | 427, 179, 122, 139 |
| 7, 179, 2, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 61 x 7 x 179 x 2 x 139 = 84993496
Therefore, the lowest common multiple of 854,716,488,556 is 84993496.
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.
854 x 716 x 488 x 556 = 165907304192
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.
854 : 1, 2, 7, 14, 61, 122, 427, 854
716 : 1, 2, 4, 179, 358, 716
488 : 1, 2, 4, 8, 61, 122, 244, 488
556 : 1, 2, 4, 139, 278, 556
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,716,488,556, is 2.
Now, the common factors can be found like this.
854:2x 7x 61
716:2x 2x 179
488:2x 2x 2x 61
556:2x 2x 139
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 2x 61 = 976
Therefore, the value for common factors is 976.
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 = 165907304192/(2x976)
LCM = 165907304192/1952
LCM = 84993496
Thus, we can understand that the LCM of 854,716,488,556 is 84993496.
