Given numbers are 822,702,126,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,702,126,782 is 263228238.
Find LCM of 822,702,126,782 with Prime Factorization
2 | 822, 702, 126, 782 |
3 | 411, 351, 63, 391 |
3 | 137, 117, 21, 391 |
137, 39, 7, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 137 x 39 x 7 x 391 = 263228238
Therefore, the lowest common multiple of 822,702,126,782 is 263228238.
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 702 x 126 x 782 = 56857299408
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
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
782 : 1, 2, 17, 23, 34, 46, 391, 782
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,702,126,782, is 2.
Now, the common factors can be found like this.
822:2x 3x 137
702:2x 3x 3x 3x 13
126:2x 3x 3x 7
782:2x 17x 23
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 56857299408/(2x108)
LCM = 56857299408/216
LCM = 263228238
Thus, we can understand that the LCM of 822,702,126,782 is 263228238.
