Find LCM of 210,606,505,678 with Prime Factorization
| 2 | 210, 606, 505, 678 |
| 3 | 105, 303, 505, 339 |
| 5 | 35, 101, 505, 113 |
| 101 | 7, 101, 101, 113 |
| 7, 1, 1, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 101 x 7 x 1 x 1 x 113 = 2396730
Therefore, the lowest common multiple of 210,606,505,678 is 2396730.
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.
210 x 606 x 505 x 678 = 43572551400
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.
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
606 : 1, 2, 3, 6, 101, 202, 303, 606
505 : 1, 5, 101, 505
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,606,505,678, is 1.
Now, the common factors can be found like this.
210:2x 3x 5x 7
606:2x 3x 101
505:5x 101
678:2x 3x 113
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 101 = 18180
Therefore, the value for common factors is 18180.
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 = 43572551400/(1x18180)
LCM = 43572551400/18180
LCM = 2396730
Thus, we can understand that the LCM of 210,606,505,678 is 2396730.
