Find LCM of 280,765,246,680,175 with Prime Factorization
| 2 | 280, 765, 246, 680, 175 |
| 2 | 140, 765, 123, 340, 175 |
| 2 | 70, 765, 123, 170, 175 |
| 3 | 35, 765, 123, 85, 175 |
| 5 | 35, 255, 41, 85, 175 |
| 7 | 7, 51, 41, 17, 35 |
| 17 | 1, 51, 41, 17, 5 |
| 1, 3, 41, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 17 x 1 x 3 x 41 x 1 x 5 = 8782200
Therefore, the lowest common multiple of 280,765,246,680,175 is 8782200.
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.
280 x 765 x 246 x 680 x 175 = 6270490800000
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
246 : 1, 2, 3, 6, 41, 82, 123, 246
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,765,246,680,175, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
765:3x 3x 5x 17
246:2x 3x 41
680:2x 2x 2x 5x 17
175:5x 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 2x 2x 2x 3x 5x 5x 5x 7x 17 = 714000
Therefore, the value for common factors is 714000.
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 = 6270490800000/(1x714000)
LCM = 6270490800000/714000
LCM = 8782200
Thus, we can understand that the LCM of 280,765,246,680,175 is 8782200.
