Find LCM of 105,938,754,245,154 with Prime Factorization
| 2 | 105, 938, 754, 245, 154 |
| 5 | 105, 469, 377, 245, 77 |
| 7 | 21, 469, 377, 49, 77 |
| 3, 67, 377, 7, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 3 x 67 x 377 x 7 x 11 = 408438030
Therefore, the lowest common multiple of 105,938,754,245,154 is 408438030.
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.
105 x 938 x 754 x 245 x 154 = 2801884885800
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
938 : 1, 2, 7, 14, 67, 134, 469, 938
754 : 1, 2, 13, 26, 29, 58, 377, 754
245 : 1, 5, 7, 35, 49, 245
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,938,754,245,154, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
938:2x 7x 67
754:2x 13x 29
245:5x 7x 7
154:2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 7x 7x 7 = 6860
Therefore, the value for common factors is 6860.
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 = 2801884885800/(1x6860)
LCM = 2801884885800/6860
LCM = 408438030
Thus, we can understand that the LCM of 105,938,754,245,154 is 408438030.
