Given numbers are 621,551,279,485
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,551,279,485 is 5144540985.
Find LCM of 621,551,279,485 with Prime Factorization
| 3 | 621, 551, 279, 485 |
| 3 | 207, 551, 93, 485 |
| 69, 551, 31, 485 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 69 x 551 x 31 x 485 = 5144540985
Therefore, the lowest common multiple of 621,551,279,485 is 5144540985.
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.
621 x 551 x 279 x 485 = 46300868865
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
551 : 1, 19, 29, 551
279 : 1, 3, 9, 31, 93, 279
485 : 1, 5, 97, 485
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,551,279,485, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
551:19x 29
279:3x 3x 31
485:5x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 46300868865/(1x9)
LCM = 46300868865/9
LCM = 5144540985
Thus, we can understand that the LCM of 621,551,279,485 is 5144540985.
