Given numbers are 822,457,781,135,225
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,457,781,135,225 is 66011799150.
Find LCM of 822,457,781,135,225 with Prime Factorization
| 3 | 822, 457, 781, 135, 225 |
| 3 | 274, 457, 781, 45, 75 |
| 5 | 274, 457, 781, 15, 25 |
| 274, 457, 781, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 274 x 457 x 781 x 3 x 5 = 66011799150
Therefore, the lowest common multiple of 822,457,781,135,225 is 66011799150.
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 457 x 781 x 135 x 225 = 8911592885250
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
457 : 1, 457
781 : 1, 11, 71, 781
135 : 1, 3, 5, 9, 15, 27, 45, 135
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,457,781,135,225, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
457:457
781:11x 71
135:3x 3x 3x 5
225:3x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 8911592885250/(1x135)
LCM = 8911592885250/135
LCM = 66011799150
Thus, we can understand that the LCM of 822,457,781,135,225 is 66011799150.
