The LCM of 765,651,186,378 is 996030.
Find LCM of 765,651,186,378 with Prime Factorization
| 2 | 765, 651, 186, 378 |
| 3 | 765, 651, 93, 189 |
| 3 | 255, 217, 31, 63 |
| 7 | 85, 217, 31, 21 |
| 31 | 85, 31, 31, 3 |
| 85, 1, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 31 x 85 x 1 x 1 x 3 = 996030
Therefore, the lowest common multiple of 765,651,186,378 is 996030.
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.
765 x 651 x 186 x 378 = 35014438620
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
651 : 1, 3, 7, 21, 31, 93, 217, 651
186 : 1, 2, 3, 6, 31, 62, 93, 186
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,651,186,378, is 3.
Now, the common factors can be found like this.
765:3x 3x 5x 17
651:3x 7x 31
186:2x 3x 31
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 3x 3x 3x 7x 31 = 11718
Therefore, the value for common factors is 11718.
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 = 35014438620/(3x11718)
LCM = 35014438620/35154
LCM = 996030
Thus, we can understand that the LCM of 765,651,186,378 is 996030.
