Find LCM of 672,656,719,399 with Prime Factorization
| 2 | 672, 656, 719, 399 |
| 2 | 336, 328, 719, 399 |
| 2 | 168, 164, 719, 399 |
| 2 | 84, 82, 719, 399 |
| 3 | 42, 41, 719, 399 |
| 7 | 14, 41, 719, 133 |
| 2, 41, 719, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 2 x 41 x 719 x 19 = 376387872
Therefore, the lowest common multiple of 672,656,719,399 is 376387872.
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.
672 x 656 x 719 x 399 = 126466324992
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.
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
719 : 1, 719
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,656,719,399, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
656:2x 2x 2x 2x 41
719:719
399:3x 7x 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 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 126466324992/(1x336)
LCM = 126466324992/336
LCM = 376387872
Thus, we can understand that the LCM of 672,656,719,399 is 376387872.
