Find LCM of 103,945,378,847,279 with Prime Factorization
| 3 | 103, 945, 378, 847, 279 |
| 3 | 103, 315, 126, 847, 93 |
| 3 | 103, 105, 42, 847, 31 |
| 7 | 103, 35, 14, 847, 31 |
| 103, 5, 2, 121, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 7 x 103 x 5 x 2 x 121 x 31 = 730207170
Therefore, the lowest common multiple of 103,945,378,847,279 is 730207170.
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.
103 x 945 x 378 x 847 x 279 = 8694576773190
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.
103 : 1, 103
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
847 : 1, 7, 11, 77, 121, 847
279 : 1, 3, 9, 31, 93, 279
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,945,378,847,279, is 1.
Now, the common factors can be found like this.
103:103
945:3x 3x 3x 5x 7
378:2x 3x 3x 3x 7
847:7x 11x 11
279:3x 3x 31
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 3x 3x 7x 7 = 11907
Therefore, the value for common factors is 11907.
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 = 8694576773190/(1x11907)
LCM = 8694576773190/11907
LCM = 730207170
Thus, we can understand that the LCM of 103,945,378,847,279 is 730207170.
