Given numbers are 355,538,345,390,426
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 355,538,345,390,426 is 171318030.
Find LCM of 355,538,345,390,426 with Prime Factorization
| 2 | 355, 538, 345, 390, 426 |
| 3 | 355, 269, 345, 195, 213 |
| 5 | 355, 269, 115, 65, 71 |
| 71 | 71, 269, 23, 13, 71 |
| 1, 269, 23, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 71 x 1 x 269 x 23 x 13 x 1 = 171318030
Therefore, the lowest common multiple of 355,538,345,390,426 is 171318030.
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.
355 x 538 x 345 x 390 x 426 = 10947222117000
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.
355 : 1, 5, 71, 355
538 : 1, 2, 269, 538
345 : 1, 3, 5, 15, 23, 69, 115, 345
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
426 : 1, 2, 3, 6, 71, 142, 213, 426
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,538,345,390,426, is 1.
Now, the common factors can be found like this.
355:5x 71
538:2x 269
345:3x 5x 23
390:2x 3x 5x 13
426:2x 3x 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 2x 3x 3x 5x 5x 71 = 63900
Therefore, the value for common factors is 63900.
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 = 10947222117000/(1x63900)
LCM = 10947222117000/63900
LCM = 171318030
Thus, we can understand that the LCM of 355,538,345,390,426 is 171318030.
