Given numbers are 869,310,660,170,264
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,310,660,170,264 is 54955560.
Find LCM of 869,310,660,170,264 with Prime Factorization
| 2 | 869, 310, 660, 170, 264 |
| 2 | 869, 155, 330, 85, 132 |
| 3 | 869, 155, 165, 85, 66 |
| 5 | 869, 155, 55, 85, 22 |
| 11 | 869, 31, 11, 17, 22 |
| 79, 31, 1, 17, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 79 x 31 x 1 x 17 x 2 = 54955560
Therefore, the lowest common multiple of 869,310,660,170,264 is 54955560.
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.
869 x 310 x 660 x 170 x 264 = 7979547312000
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.
869 : 1, 11, 79, 869
310 : 1, 2, 5, 10, 31, 62, 155, 310
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
170 : 1, 2, 5, 10, 17, 34, 85, 170
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,310,660,170,264, is 1.
Now, the common factors can be found like this.
869:11x 79
310:2x 5x 31
660:2x 2x 3x 5x 11
170:2x 5x 17
264:2x 2x 2x 3x 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 5x 5x 11x 11 = 145200
Therefore, the value for common factors is 145200.
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 = 7979547312000/(1x145200)
LCM = 7979547312000/145200
LCM = 54955560
Thus, we can understand that the LCM of 869,310,660,170,264 is 54955560.
