The LCM of 345,736,420,424 is 4095840.
Find LCM of 345,736,420,424 with Prime Factorization
| 2 | 345, 736, 420, 424 |
| 2 | 345, 368, 210, 212 |
| 2 | 345, 184, 105, 106 |
| 3 | 345, 92, 105, 53 |
| 5 | 115, 92, 35, 53 |
| 23 | 23, 92, 7, 53 |
| 1, 4, 7, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 23 x 1 x 4 x 7 x 53 = 4095840
Therefore, the lowest common multiple of 345,736,420,424 is 4095840.
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.
345 x 736 x 420 x 424 = 45218073600
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
424 : 1, 2, 4, 8, 53, 106, 212, 424
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,736,420,424, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
736:2x 2x 2x 2x 2x 23
420:2x 2x 3x 5x 7
424:2x 2x 2x 53
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 23 = 11040
Therefore, the value for common factors is 11040.
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 = 45218073600/(1x11040)
LCM = 45218073600/11040
LCM = 4095840
Thus, we can understand that the LCM of 345,736,420,424 is 4095840.
