Find LCM of 260,432,978,249,705 with Prime Factorization
2 | 260, 432, 978, 249, 705 |
2 | 130, 216, 489, 249, 705 |
3 | 65, 108, 489, 249, 705 |
5 | 65, 36, 163, 83, 235 |
13, 36, 163, 83, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 36 x 163 x 83 x 47 = 17855033040
Therefore, the lowest common multiple of 260,432,978,249,705 is 17855033040.
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.
260 x 432 x 978 x 249 x 705 = 19283435683200
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.
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
978 : 1, 2, 3, 6, 163, 326, 489, 978
249 : 1, 3, 83, 249
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,432,978,249,705, is 1.
Now, the common factors can be found like this.
260:2x 2x 5x 13
432:2x 2x 2x 2x 3x 3x 3
978:2x 3x 163
249:3x 83
705:3x 5x 47
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 5 = 1080
Therefore, the value for common factors is 1080.
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 = 19283435683200/(1x1080)
LCM = 19283435683200/1080
LCM = 17855033040
Thus, we can understand that the LCM of 260,432,978,249,705 is 17855033040.
