The LCM of 822,505,952,945 is 1778331240.
Find LCM of 822,505,952,945 with Prime Factorization
| 2 | 822, 505, 952, 945 |
| 3 | 411, 505, 476, 945 |
| 5 | 137, 505, 476, 315 |
| 7 | 137, 101, 476, 63 |
| 137, 101, 68, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 137 x 101 x 68 x 9 = 1778331240
Therefore, the lowest common multiple of 822,505,952,945 is 1778331240.
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 505 x 952 x 945 = 373449560400
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
505 : 1, 5, 101, 505
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,505,952,945, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
505:5x 101
952:2x 2x 2x 7x 17
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 373449560400/(1x210)
LCM = 373449560400/210
LCM = 1778331240
Thus, we can understand that the LCM of 822,505,952,945 is 1778331240.
