Given numbers are 203,568,493,142
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 203,568,493,142 is 1960168.
Find LCM of 203,568,493,142 with Prime Factorization
| 2 | 203, 568, 493, 142 |
| 29 | 203, 284, 493, 71 |
| 71 | 7, 284, 17, 71 |
| 7, 4, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 71 x 7 x 4 x 17 x 1 = 1960168
Therefore, the lowest common multiple of 203,568,493,142 is 1960168.
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.
203 x 568 x 493 x 142 = 8071971824
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.
203 : 1, 7, 29, 203
568 : 1, 2, 4, 8, 71, 142, 284, 568
493 : 1, 17, 29, 493
142 : 1, 2, 71, 142
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,568,493,142, is 1.
Now, the common factors can be found like this.
203:7x 29
568:2x 2x 2x 71
493:17x 29
142:2x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 29x 71 = 4118
Therefore, the value for common factors is 4118.
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 = 8071971824/(1x4118)
LCM = 8071971824/4118
LCM = 1960168
Thus, we can understand that the LCM of 203,568,493,142 is 1960168.
