Find LCM of 692,384,389,768 with Prime Factorization
2 | 692, 384, 389, 768 |
2 | 346, 192, 389, 384 |
2 | 173, 96, 389, 192 |
2 | 173, 48, 389, 96 |
2 | 173, 24, 389, 48 |
2 | 173, 12, 389, 24 |
2 | 173, 6, 389, 12 |
3 | 173, 3, 389, 6 |
173, 1, 389, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 173 x 1 x 389 x 2 = 51684096
Therefore, the lowest common multiple of 692,384,389,768 is 51684096.
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.
692 x 384 x 389 x 768 = 79386771456
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.
692 : 1, 2, 4, 173, 346, 692
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
389 : 1, 389
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 692,384,389,768, is 1.
Now, the common factors can be found like this.
692:2x 2x 173
384:2x 2x 2x 2x 2x 2x 2x 3
389:389
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 3 = 1536
Therefore, the value for common factors is 1536.
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 = 79386771456/(1x1536)
LCM = 79386771456/1536
LCM = 51684096
Thus, we can understand that the LCM of 692,384,389,768 is 51684096.
