Given numbers are 845,920,661,322,558
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,920,661,322,558 is 200714262840.
Find LCM of 845,920,661,322,558 with Prime Factorization
| 2 | 845, 920, 661, 322, 558 |
| 5 | 845, 460, 661, 161, 279 |
| 23 | 169, 92, 661, 161, 279 |
| 169, 4, 661, 7, 279 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 169 x 4 x 661 x 7 x 279 = 200714262840
Therefore, the lowest common multiple of 845,920,661,322,558 is 200714262840.
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.
845 x 920 x 661 x 322 x 558 = 92328560906400
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.
845 : 1, 5, 13, 65, 169, 845
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
661 : 1, 661
322 : 1, 2, 7, 14, 23, 46, 161, 322
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,920,661,322,558, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
920:2x 2x 2x 5x 23
661:661
322:2x 7x 23
558:2x 3x 3x 31
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 5x 23 = 460
Therefore, the value for common factors is 460.
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 = 92328560906400/(1x460)
LCM = 92328560906400/460
LCM = 200714262840
Thus, we can understand that the LCM of 845,920,661,322,558 is 200714262840.
