Given numbers are 202,514,642,140,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 202,514,642,140,245 is 8165553060.
Find LCM of 202,514,642,140,245 with Prime Factorization
| 2 | 202, 514, 642, 140, 245 |
| 5 | 101, 257, 321, 70, 245 |
| 7 | 101, 257, 321, 14, 49 |
| 101, 257, 321, 2, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 101 x 257 x 321 x 2 x 7 = 8165553060
Therefore, the lowest common multiple of 202,514,642,140,245 is 8165553060.
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.
202 x 514 x 642 x 140 x 245 = 2286354856800
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.
202 : 1, 2, 101, 202
514 : 1, 2, 257, 514
642 : 1, 2, 3, 6, 107, 214, 321, 642
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,514,642,140,245, is 1.
Now, the common factors can be found like this.
202:2x 101
514:2x 257
642:2x 3x 107
140:2x 2x 5x 7
245:5x 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 2x 2x 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 2286354856800/(1x280)
LCM = 2286354856800/280
LCM = 8165553060
Thus, we can understand that the LCM of 202,514,642,140,245 is 8165553060.
