Given numbers are 629,642,189,612
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 629,642,189,612 is 50881068.
Find LCM of 629,642,189,612 with Prime Factorization
| 2 | 629, 642, 189, 612 |
| 3 | 629, 321, 189, 306 |
| 3 | 629, 107, 63, 102 |
| 17 | 629, 107, 21, 34 |
| 37, 107, 21, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 37 x 107 x 21 x 2 = 50881068
Therefore, the lowest common multiple of 629,642,189,612 is 50881068.
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.
629 x 642 x 189 x 612 = 46708820424
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.
629 : 1, 17, 37, 629
642 : 1, 2, 3, 6, 107, 214, 321, 642
189 : 1, 3, 7, 9, 21, 27, 63, 189
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,642,189,612, is 1.
Now, the common factors can be found like this.
629:17x 37
642:2x 3x 107
189:3x 3x 3x 7
612:2x 2x 3x 3x 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 3x 3x 3x 17 = 918
Therefore, the value for common factors is 918.
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 = 46708820424/(1x918)
LCM = 46708820424/918
LCM = 50881068
Thus, we can understand that the LCM of 629,642,189,612 is 50881068.
