Find LCM of 639,260,252,182,585 with Prime Factorization
| 2 | 639, 260, 252, 182, 585 |
| 2 | 639, 130, 126, 91, 585 |
| 3 | 639, 65, 63, 91, 585 |
| 3 | 213, 65, 21, 91, 195 |
| 5 | 71, 65, 7, 91, 65 |
| 7 | 71, 13, 7, 91, 13 |
| 13 | 71, 13, 1, 13, 13 |
| 71, 1, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 13 x 71 x 1 x 1 x 1 x 1 = 1162980
Therefore, the lowest common multiple of 639,260,252,182,585 is 1162980.
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.
639 x 260 x 252 x 182 x 585 = 4457609301600
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.
639 : 1, 3, 9, 71, 213, 639
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
182 : 1, 2, 7, 13, 14, 26, 91, 182
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,260,252,182,585, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
260:2x 2x 5x 13
252:2x 2x 3x 3x 7
182:2x 7x 13
585:3x 3x 5x 13
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 2x 3x 3x 3x 3x 5x 7x 13x 13 = 3832920
Therefore, the value for common factors is 3832920.
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 = 4457609301600/(1x3832920)
LCM = 4457609301600/3832920
LCM = 1162980
Thus, we can understand that the LCM of 639,260,252,182,585 is 1162980.
