Find LCM of 220,240,836,407,834 with Prime Factorization
| 2 | 220, 240, 836, 407, 834 |
| 2 | 110, 120, 418, 407, 417 |
| 3 | 55, 60, 209, 407, 417 |
| 5 | 55, 20, 209, 407, 139 |
| 11 | 11, 4, 209, 407, 139 |
| 1, 4, 19, 37, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 1 x 4 x 19 x 37 x 139 = 257972880
Therefore, the lowest common multiple of 220,240,836,407,834 is 257972880.
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.
220 x 240 x 836 x 407 x 834 = 14983064870400
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
407 : 1, 11, 37, 407
834 : 1, 2, 3, 6, 139, 278, 417, 834
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,240,836,407,834, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
240:2x 2x 2x 2x 3x 5
836:2x 2x 11x 19
407:11x 37
834:2x 3x 139
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 11x 11 = 58080
Therefore, the value for common factors is 58080.
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 = 14983064870400/(1x58080)
LCM = 14983064870400/58080
LCM = 257972880
Thus, we can understand that the LCM of 220,240,836,407,834 is 257972880.
