Given numbers are 568,793,989,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 568,793,989,980 is 109139987320.
Find LCM of 568,793,989,980 with Prime Factorization
| 2 | 568, 793, 989, 980 |
| 2 | 284, 793, 989, 490 |
| 142, 793, 989, 245 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 142 x 793 x 989 x 245 = 109139987320
Therefore, the lowest common multiple of 568,793,989,980 is 109139987320.
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.
568 x 793 x 989 x 980 = 436559949280
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.
568 : 1, 2, 4, 8, 71, 142, 284, 568
793 : 1, 13, 61, 793
989 : 1, 23, 43, 989
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 568,793,989,980, is 1.
Now, the common factors can be found like this.
568:2x 2x 2x 71
793:13x 61
989:23x 43
980:2x 2x 5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 436559949280/(1x4)
LCM = 436559949280/4
LCM = 109139987320
Thus, we can understand that the LCM of 568,793,989,980 is 109139987320.
