Given numbers are 282,245,693,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 282,245,693,847 is 25079670.
Find LCM of 282,245,693,847 with Prime Factorization
| 3 | 282, 245, 693, 847 |
| 7 | 94, 245, 231, 847 |
| 11 | 94, 35, 33, 121 |
| 94, 35, 3, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 94 x 35 x 3 x 11 = 25079670
Therefore, the lowest common multiple of 282,245,693,847 is 25079670.
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.
282 x 245 x 693 x 847 = 40553826390
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.
282 : 1, 2, 3, 6, 47, 94, 141, 282
245 : 1, 5, 7, 35, 49, 245
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,245,693,847, is 1.
Now, the common factors can be found like this.
282:2x 3x 47
245:5x 7x 7
693:3x 3x 7x 11
847:7x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 11 = 1617
Therefore, the value for common factors is 1617.
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 = 40553826390/(1x1617)
LCM = 40553826390/1617
LCM = 25079670
Thus, we can understand that the LCM of 282,245,693,847 is 25079670.
