Given numbers are 193,546,358,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 193,546,358,721 is 1942854186.
Find LCM of 193,546,358,721 with Prime Factorization
| 2 | 193, 546, 358, 721 |
| 7 | 193, 273, 179, 721 |
| 193, 39, 179, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 193 x 39 x 179 x 103 = 1942854186
Therefore, the lowest common multiple of 193,546,358,721 is 1942854186.
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.
193 x 546 x 358 x 721 = 27199958604
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.
193 : 1, 193
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
358 : 1, 2, 179, 358
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 193,546,358,721, is 1.
Now, the common factors can be found like this.
193:193
546:2x 3x 7x 13
358:2x 179
721:7x 103
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 = 27199958604/(1x14)
LCM = 27199958604/14
LCM = 1942854186
Thus, we can understand that the LCM of 193,546,358,721 is 1942854186.
