Find LCM of 180,686,540,476 with Prime Factorization
| 2 | 180, 686, 540, 476 |
| 2 | 90, 343, 270, 238 |
| 3 | 45, 343, 135, 119 |
| 3 | 15, 343, 45, 119 |
| 5 | 5, 343, 15, 119 |
| 7 | 1, 343, 3, 119 |
| 1, 49, 3, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 1 x 49 x 3 x 17 = 3148740
Therefore, the lowest common multiple of 180,686,540,476 is 3148740.
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.
180 x 686 x 540 x 476 = 31739299200
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
686 : 1, 2, 7, 14, 49, 98, 343, 686
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,686,540,476, is 2.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
686:2x 7x 7x 7
540:2x 2x 3x 3x 3x 5
476:2x 2x 7x 17
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 3x 3x 5x 7 = 5040
Therefore, the value for common factors is 5040.
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 = 31739299200/(2x5040)
LCM = 31739299200/10080
LCM = 3148740
Thus, we can understand that the LCM of 180,686,540,476 is 3148740.
