Given numbers are 692,777,728,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 692,777,728,660 is 768888120.
Find LCM of 692,777,728,660 with Prime Factorization
| 2 | 692, 777, 728, 660 |
| 2 | 346, 777, 364, 330 |
| 3 | 173, 777, 182, 165 |
| 7 | 173, 259, 182, 55 |
| 173, 37, 26, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 173 x 37 x 26 x 55 = 768888120
Therefore, the lowest common multiple of 692,777,728,660 is 768888120.
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 777 x 728 x 660 = 258346408320
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
777 : 1, 3, 7, 21, 37, 111, 259, 777
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 692,777,728,660, is 1.
Now, the common factors can be found like this.
692:2x 2x 173
777:3x 7x 37
728:2x 2x 2x 7x 13
660:2x 2x 3x 5x 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 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 = 258346408320/(1x336)
LCM = 258346408320/336
LCM = 768888120
Thus, we can understand that the LCM of 692,777,728,660 is 768888120.
