Find LCM of 442,978,231,221,577 with Prime Factorization
| 2 | 442, 978, 231, 221, 577 |
| 3 | 221, 489, 231, 221, 577 |
| 13 | 221, 163, 77, 221, 577 |
| 17 | 17, 163, 77, 17, 577 |
| 1, 163, 77, 1, 577 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 1 x 163 x 77 x 1 x 577 = 9602795202
Therefore, the lowest common multiple of 442,978,231,221,577 is 9602795202.
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.
442 x 978 x 231 x 221 x 577 = 12733306437852
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
978 : 1, 2, 3, 6, 163, 326, 489, 978
231 : 1, 3, 7, 11, 21, 33, 77, 231
221 : 1, 13, 17, 221
577 : 1, 577
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,978,231,221,577, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
978:2x 3x 163
231:3x 7x 11
221:13x 17
577:577
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 13x 17 = 1326
Therefore, the value for common factors is 1326.
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 = 12733306437852/(1x1326)
LCM = 12733306437852/1326
LCM = 9602795202
Thus, we can understand that the LCM of 442,978,231,221,577 is 9602795202.
