Given numbers are 822,548,491
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,548,491 is 807204.
Find LCM of 822,548,491 with Prime Factorization
| 2 | 822, 548, 491 |
| 137 | 411, 274, 491 |
| 3, 2, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 137 x 3 x 2 x 491 = 807204
Therefore, the lowest common multiple of 822,548,491 is 807204.
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.
822 x 548 x 491 = 221173896
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
548 : 1, 2, 4, 137, 274, 548
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,548,491, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
548:2x 2x 137
491:491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 137 = 274
Therefore, the value for common factors is 274.
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 = 221173896/(1x274)
LCM = 221173896/274
LCM = 807204
Thus, we can understand that the LCM of 822,548,491 is 807204.
