Find LCM of 635,394,665,981,210 with Prime Factorization
| 2 | 635, 394, 665, 981, 210 |
| 3 | 635, 197, 665, 981, 105 |
| 5 | 635, 197, 665, 327, 35 |
| 7 | 127, 197, 133, 327, 7 |
| 127, 197, 19, 327, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 127 x 197 x 19 x 327 x 1 = 32643039870
Therefore, the lowest common multiple of 635,394,665,981,210 is 32643039870.
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.
635 x 394 x 665 x 981 x 210 = 34275191863500
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.
635 : 1, 5, 127, 635
394 : 1, 2, 197, 394
665 : 1, 5, 7, 19, 35, 95, 133, 665
981 : 1, 3, 9, 109, 327, 981
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,394,665,981,210, is 1.
Now, the common factors can be found like this.
635:5x 127
394:2x 197
665:5x 7x 19
981:3x 3x 109
210:2x 3x 5x 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 3x 5x 5x 7 = 1050
Therefore, the value for common factors is 1050.
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 = 34275191863500/(1x1050)
LCM = 34275191863500/1050
LCM = 32643039870
Thus, we can understand that the LCM of 635,394,665,981,210 is 32643039870.
