Find LCM of 823,785,434,942,245 with Prime Factorization
| 2 | 823, 785, 434, 942, 245 |
| 5 | 823, 785, 217, 471, 245 |
| 7 | 823, 157, 217, 471, 49 |
| 157 | 823, 157, 31, 471, 7 |
| 823, 1, 31, 3, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 157 x 823 x 1 x 31 x 3 x 7 = 5888145270
Therefore, the lowest common multiple of 823,785,434,942,245 is 5888145270.
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.
823 x 785 x 434 x 942 x 245 = 64710716517300
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.
823 : 1, 823
785 : 1, 5, 157, 785
434 : 1, 2, 7, 14, 31, 62, 217, 434
942 : 1, 2, 3, 6, 157, 314, 471, 942
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,785,434,942,245, is 1.
Now, the common factors can be found like this.
823:823
785:5x 157
434:2x 7x 31
942:2x 3x 157
245:5x 7x 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 5x 7x 157 = 10990
Therefore, the value for common factors is 10990.
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 = 64710716517300/(1x10990)
LCM = 64710716517300/10990
LCM = 5888145270
Thus, we can understand that the LCM of 823,785,434,942,245 is 5888145270.
