Given numbers are 195,622,252,378
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 195,622,252,378 is 15282540.
Find LCM of 195,622,252,378 with Prime Factorization
2 | 195, 622, 252, 378 |
3 | 195, 311, 126, 189 |
3 | 65, 311, 42, 63 |
7 | 65, 311, 14, 21 |
65, 311, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 65 x 311 x 2 x 3 = 15282540
Therefore, the lowest common multiple of 195,622,252,378 is 15282540.
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.
195 x 622 x 252 x 378 = 11553600240
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.
195 : 1, 3, 5, 13, 15, 39, 65, 195
622 : 1, 2, 311, 622
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 195,622,252,378, is 1.
Now, the common factors can be found like this.
195:3x 5x 13
622:2x 311
252:2x 2x 3x 3x 7
378:2x 3x 3x 3x 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 2x 3x 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 11553600240/(1x756)
LCM = 11553600240/756
LCM = 15282540
Thus, we can understand that the LCM of 195,622,252,378 is 15282540.
