Find LCM of 392,243,968,728,751 with Prime Factorization
2 | 392, 243, 968, 728, 751 |
2 | 196, 243, 484, 364, 751 |
2 | 98, 243, 242, 182, 751 |
7 | 49, 243, 121, 91, 751 |
7, 243, 121, 13, 751 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 243 x 121 x 13 x 751 = 112528103688
Therefore, the lowest common multiple of 392,243,968,728,751 is 112528103688.
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.
392 x 243 x 968 x 728 x 751 = 50412590452224
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
243 : 1, 3, 9, 27, 81, 243
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
751 : 1, 751
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,243,968,728,751, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
243:3x 3x 3x 3x 3
968:2x 2x 2x 11x 11
728:2x 2x 2x 7x 13
751:751
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 2x 2x 2x 2x 7 = 448
Therefore, the value for common factors is 448.
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 = 50412590452224/(1x448)
LCM = 50412590452224/448
LCM = 112528103688
Thus, we can understand that the LCM of 392,243,968,728,751 is 112528103688.
