The LCM of 678,763,392,176 is 318665424.
Find LCM of 678,763,392,176 with Prime Factorization
| 2 | 678, 763, 392, 176 |
| 2 | 339, 763, 196, 88 |
| 2 | 339, 763, 98, 44 |
| 7 | 339, 763, 49, 22 |
| 339, 109, 7, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 339 x 109 x 7 x 22 = 318665424
Therefore, the lowest common multiple of 678,763,392,176 is 318665424.
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.
678 x 763 x 392 x 176 = 35690527488
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
763 : 1, 7, 109, 763
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,763,392,176, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
763:7x 109
392:2x 2x 2x 7x 7
176:2x 2x 2x 2x 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 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 35690527488/(1x112)
LCM = 35690527488/112
LCM = 318665424
Thus, we can understand that the LCM of 678,763,392,176 is 318665424.
