Given numbers are 789,494,461,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,494,461,621 is 37194200082.
Find LCM of 789,494,461,621 with Prime Factorization
| 3 | 789, 494, 461, 621 |
| 263, 494, 461, 207 |
Multiply the prime numbers at the bottom and the left side.
3 x 263 x 494 x 461 x 207 = 37194200082
Therefore, the lowest common multiple of 789,494,461,621 is 37194200082.
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.
789 x 494 x 461 x 621 = 111582600246
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.
789 : 1, 3, 263, 789
494 : 1, 2, 13, 19, 26, 38, 247, 494
461 : 1, 461
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,494,461,621, is 1.
Now, the common factors can be found like this.
789:3x 263
494:2x 13x 19
461:461
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 111582600246/(1x3)
LCM = 111582600246/3
LCM = 37194200082
Thus, we can understand that the LCM of 789,494,461,621 is 37194200082.
