Find LCM of 808,189,420,435 with Prime Factorization
| 2 | 808, 189, 420, 435 |
| 2 | 404, 189, 210, 435 |
| 3 | 202, 189, 105, 435 |
| 5 | 202, 63, 35, 145 |
| 7 | 202, 63, 7, 29 |
| 202, 9, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 202 x 9 x 1 x 29 = 22143240
Therefore, the lowest common multiple of 808,189,420,435 is 22143240.
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.
808 x 189 x 420 x 435 = 27900482400
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
189 : 1, 3, 7, 9, 21, 27, 63, 189
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
435 : 1, 3, 5, 15, 29, 87, 145, 435
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,189,420,435, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
189:3x 3x 3x 7
420:2x 2x 3x 5x 7
435:3x 5x 29
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 3x 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 27900482400/(1x1260)
LCM = 27900482400/1260
LCM = 22143240
Thus, we can understand that the LCM of 808,189,420,435 is 22143240.
