Given numbers are 105,202,197,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,202,197,393 is 547366470.
Find LCM of 105,202,197,393 with Prime Factorization
| 3 | 105, 202, 197, 393 |
| 35, 202, 197, 131 |
Multiply the prime numbers at the bottom and the left side.
3 x 35 x 202 x 197 x 131 = 547366470
Therefore, the lowest common multiple of 105,202,197,393 is 547366470.
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.
105 x 202 x 197 x 393 = 1642099410
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
202 : 1, 2, 101, 202
197 : 1, 197
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,202,197,393, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
202:2x 101
197:197
393:3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 1642099410/(1x3)
LCM = 1642099410/3
LCM = 547366470
Thus, we can understand that the LCM of 105,202,197,393 is 547366470.
