Find LCM of 968,728,278,784,928 with Prime Factorization
| 2 | 968, 728, 278, 784, 928 |
| 2 | 484, 364, 139, 392, 464 |
| 2 | 242, 182, 139, 196, 232 |
| 2 | 121, 91, 139, 98, 116 |
| 7 | 121, 91, 139, 49, 58 |
| 121, 13, 139, 7, 58 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 121 x 13 x 139 x 7 x 58 = 9942316384
Therefore, the lowest common multiple of 968,728,278,784,928 is 9942316384.
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.
968 x 728 x 278 x 784 x 928 = 142533047681024
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.
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
278 : 1, 2, 139, 278
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 968,728,278,784,928, is 2.
Now, the common factors can be found like this.
968:2x 2x 2x 11x 11
728:2x 2x 2x 7x 13
278:2x 139
784:2x 2x 2x 2x 7x 7
928:2x 2x 2x 2x 2x 29
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 2x 2x 2x 2x 7 = 7168
Therefore, the value for common factors is 7168.
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 = 142533047681024/(2x7168)
LCM = 142533047681024/14336
LCM = 9942316384
Thus, we can understand that the LCM of 968,728,278,784,928 is 9942316384.
