Given numbers are 269,847,686,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 269,847,686,284 is 3170663188.
Find LCM of 269,847,686,284 with Prime Factorization
| 2 | 269, 847, 686, 284 |
| 7 | 269, 847, 343, 142 |
| 269, 121, 49, 142 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 269 x 121 x 49 x 142 = 3170663188
Therefore, the lowest common multiple of 269,847,686,284 is 3170663188.
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.
269 x 847 x 686 x 284 = 44389284632
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.
269 : 1, 269
847 : 1, 7, 11, 77, 121, 847
686 : 1, 2, 7, 14, 49, 98, 343, 686
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 269,847,686,284, is 1.
Now, the common factors can be found like this.
269:269
847:7x 11x 11
686:2x 7x 7x 7
284:2x 2x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 44389284632/(1x14)
LCM = 44389284632/14
LCM = 3170663188
Thus, we can understand that the LCM of 269,847,686,284 is 3170663188.
