Find LCM of 315,276,140,280,710 with Prime Factorization
| 2 | 315, 276, 140, 280, 710 |
| 2 | 315, 138, 70, 140, 355 |
| 3 | 315, 69, 35, 70, 355 |
| 5 | 105, 23, 35, 70, 355 |
| 7 | 21, 23, 7, 14, 71 |
| 3, 23, 1, 2, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 3 x 23 x 1 x 2 x 71 = 4115160
Therefore, the lowest common multiple of 315,276,140,280,710 is 4115160.
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.
315 x 276 x 140 x 280 x 710 = 2419714080000
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
710 : 1, 2, 5, 10, 71, 142, 355, 710
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,276,140,280,710, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
276:2x 2x 3x 23
140:2x 2x 5x 7
280:2x 2x 2x 5x 7
710:2x 5x 71
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 2x 3x 5x 5x 5x 7x 7 = 588000
Therefore, the value for common factors is 588000.
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 = 2419714080000/(1x588000)
LCM = 2419714080000/588000
LCM = 4115160
Thus, we can understand that the LCM of 315,276,140,280,710 is 4115160.
