Given numbers are 623,546,231,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 623,546,231,643 is 343705362.
Find LCM of 623,546,231,643 with Prime Factorization
3 | 623, 546, 231, 643 |
7 | 623, 182, 77, 643 |
89, 26, 11, 643 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 89 x 26 x 11 x 643 = 343705362
Therefore, the lowest common multiple of 623,546,231,643 is 343705362.
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.
623 x 546 x 231 x 643 = 50524688214
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.
623 : 1, 7, 89, 623
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
231 : 1, 3, 7, 11, 21, 33, 77, 231
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,546,231,643, is 1.
Now, the common factors can be found like this.
623:7x 89
546:2x 3x 7x 13
231:3x 7x 11
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 50524688214/(1x147)
LCM = 50524688214/147
LCM = 343705362
Thus, we can understand that the LCM of 623,546,231,643 is 343705362.
