Find LCM of 392,912,651,969 with Prime Factorization
| 2 | 392, 912, 651, 969 |
| 2 | 196, 456, 651, 969 |
| 2 | 98, 228, 651, 969 |
| 3 | 49, 114, 651, 969 |
| 7 | 49, 38, 217, 323 |
| 19 | 7, 38, 31, 323 |
| 7, 2, 31, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 19 x 7 x 2 x 31 x 17 = 23550576
Therefore, the lowest common multiple of 392,912,651,969 is 23550576.
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 912 x 651 x 969 = 225520315776
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
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
651 : 1, 3, 7, 21, 31, 93, 217, 651
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,912,651,969, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
912:2x 2x 2x 2x 3x 19
651:3x 7x 31
969:3x 17x 19
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 3x 3x 7x 19 = 9576
Therefore, the value for common factors is 9576.
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 = 225520315776/(1x9576)
LCM = 225520315776/9576
LCM = 23550576
Thus, we can understand that the LCM of 392,912,651,969 is 23550576.
