Given numbers are 781,811,822,570,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,811,822,570,845 is 8358994039110.
Find LCM of 781,811,822,570,845 with Prime Factorization
| 2 | 781, 811, 822, 570, 845 |
| 3 | 781, 811, 411, 285, 845 |
| 5 | 781, 811, 137, 95, 845 |
| 781, 811, 137, 19, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 781 x 811 x 137 x 19 x 169 = 8358994039110
Therefore, the lowest common multiple of 781,811,822,570,845 is 8358994039110.
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.
781 x 811 x 822 x 570 x 845 = 250769821173300
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.
781 : 1, 11, 71, 781
811 : 1, 811
822 : 1, 2, 3, 6, 137, 274, 411, 822
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,811,822,570,845, is 1.
Now, the common factors can be found like this.
781:11x 71
811:811
822:2x 3x 137
570:2x 3x 5x 19
845:5x 13x 13
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 5 = 30
Therefore, the value for common factors is 30.
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 = 250769821173300/(1x30)
LCM = 250769821173300/30
LCM = 8358994039110
Thus, we can understand that the LCM of 781,811,822,570,845 is 8358994039110.
