Given numbers are 561,983,867,589,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,983,867,589,620 is 110435980380.
Find LCM of 561,983,867,589,620 with Prime Factorization
| 3 | 561, 983, 867, 589, 620 |
| 17 | 187, 983, 289, 589, 620 |
| 31 | 11, 983, 17, 589, 620 |
| 11, 983, 17, 19, 20 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 31 x 11 x 983 x 17 x 19 x 20 = 110435980380
Therefore, the lowest common multiple of 561,983,867,589,620 is 110435980380.
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.
561 x 983 x 867 x 589 x 620 = 174599284980780
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
983 : 1, 983
867 : 1, 3, 17, 51, 289, 867
589 : 1, 19, 31, 589
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,983,867,589,620, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
983:983
867:3x 17x 17
589:19x 31
620:2x 2x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17x 31 = 1581
Therefore, the value for common factors is 1581.
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 = 174599284980780/(1x1581)
LCM = 174599284980780/1581
LCM = 110435980380
Thus, we can understand that the LCM of 561,983,867,589,620 is 110435980380.
