Find LCM of 477,138,836,432,660 with Prime Factorization
| 2 | 477, 138, 836, 432, 660 |
| 2 | 477, 69, 418, 216, 330 |
| 3 | 477, 69, 209, 108, 165 |
| 3 | 159, 23, 209, 36, 55 |
| 11 | 53, 23, 209, 12, 55 |
| 53, 23, 19, 12, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 53 x 23 x 19 x 12 x 5 = 550305360
Therefore, the lowest common multiple of 477,138,836,432,660 is 550305360.
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.
477 x 138 x 836 x 432 x 660 = 15690306424320
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.
477 : 1, 3, 9, 53, 159, 477
138 : 1, 2, 3, 6, 23, 46, 69, 138
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 477,138,836,432,660, is 1.
Now, the common factors can be found like this.
477:3x 3x 53
138:2x 3x 23
836:2x 2x 11x 19
432:2x 2x 2x 2x 3x 3x 3
660:2x 2x 3x 5x 11
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 3x 3x 3x 11 = 28512
Therefore, the value for common factors is 28512.
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 = 15690306424320/(1x28512)
LCM = 15690306424320/28512
LCM = 550305360
Thus, we can understand that the LCM of 477,138,836,432,660 is 550305360.
