Given numbers are 692,748,272,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 692,748,272,768 is 24845568.
Find LCM of 692,748,272,768 with Prime Factorization
| 2 | 692, 748, 272, 768 |
| 2 | 346, 374, 136, 384 |
| 2 | 173, 187, 68, 192 |
| 2 | 173, 187, 34, 96 |
| 17 | 173, 187, 17, 48 |
| 173, 11, 1, 48 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 17 x 173 x 11 x 1 x 48 = 24845568
Therefore, the lowest common multiple of 692,748,272,768 is 24845568.
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 748 x 272 x 768 = 108127911936
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
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 692,748,272,768, is 4.
Now, the common factors can be found like this.
692:2x 2x 173
748:2x 2x 11x 17
272:2x 2x 2x 2x 17
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 17 = 1088
Therefore, the value for common factors is 1088.
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 = 108127911936/(4x1088)
LCM = 108127911936/4352
LCM = 24845568
Thus, we can understand that the LCM of 692,748,272,768 is 24845568.
