Given numbers are 394,661,434,399,475
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 394,661,434,399,475 is 80532703650.
Find LCM of 394,661,434,399,475 with Prime Factorization
| 2 | 394, 661, 434, 399, 475 |
| 7 | 197, 661, 217, 399, 475 |
| 19 | 197, 661, 31, 57, 475 |
| 197, 661, 31, 3, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 197 x 661 x 31 x 3 x 25 = 80532703650
Therefore, the lowest common multiple of 394,661,434,399,475 is 80532703650.
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.
394 x 661 x 434 x 399 x 475 = 21421699170900
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.
394 : 1, 2, 197, 394
661 : 1, 661
434 : 1, 2, 7, 14, 31, 62, 217, 434
399 : 1, 3, 7, 19, 21, 57, 133, 399
475 : 1, 5, 19, 25, 95, 475
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,661,434,399,475, is 1.
Now, the common factors can be found like this.
394:2x 197
661:661
434:2x 7x 31
399:3x 7x 19
475:5x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 19 = 266
Therefore, the value for common factors is 266.
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 = 21421699170900/(1x266)
LCM = 21421699170900/266
LCM = 80532703650
Thus, we can understand that the LCM of 394,661,434,399,475 is 80532703650.
