Given numbers are 822,222,456,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,222,456,836 is 25426104.
Find LCM of 822,222,456,836 with Prime Factorization
| 2 | 822, 222, 456, 836 |
| 2 | 411, 111, 228, 418 |
| 3 | 411, 111, 114, 209 |
| 19 | 137, 37, 38, 209 |
| 137, 37, 2, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 137 x 37 x 2 x 11 = 25426104
Therefore, the lowest common multiple of 822,222,456,836 is 25426104.
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 222 x 456 x 836 = 69565820544
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
222 : 1, 2, 3, 6, 37, 74, 111, 222
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,222,456,836, is 2.
Now, the common factors can be found like this.
822:2x 3x 137
222:2x 3x 37
456:2x 2x 2x 3x 19
836:2x 2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 19 = 1368
Therefore, the value for common factors is 1368.
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 = 69565820544/(2x1368)
LCM = 69565820544/2736
LCM = 25426104
Thus, we can understand that the LCM of 822,222,456,836 is 25426104.
