Given numbers are 643,312,822,137
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,312,822,137 is 27484392.
Find LCM of 643,312,822,137 with Prime Factorization
2 | 643, 312, 822, 137 |
3 | 643, 156, 411, 137 |
137 | 643, 52, 137, 137 |
643, 52, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 137 x 643 x 52 x 1 x 1 = 27484392
Therefore, the lowest common multiple of 643,312,822,137 is 27484392.
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.
643 x 312 x 822 x 137 = 22592170224
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.
643 : 1, 643
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
822 : 1, 2, 3, 6, 137, 274, 411, 822
137 : 1, 137
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,312,822,137, is 1.
Now, the common factors can be found like this.
643:643
312:2x 2x 2x 3x 13
822:2x 3x 137
137:137
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 137 = 822
Therefore, the value for common factors is 822.
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 = 22592170224/(1x822)
LCM = 22592170224/822
LCM = 27484392
Thus, we can understand that the LCM of 643,312,822,137 is 27484392.
