Given numbers are 793,686,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 793,686,221 is 9247966.
Find LCM of 793,686,221 with Prime Factorization
| 13 | 793, 686, 221 |
| 61, 686, 17 |
Multiply the prime numbers at the bottom and the left side.
13 x 61 x 686 x 17 = 9247966
Therefore, the lowest common multiple of 793,686,221 is 9247966.
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.
793 x 686 x 221 = 120223558
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.
793 : 1, 13, 61, 793
686 : 1, 2, 7, 14, 49, 98, 343, 686
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,686,221, is 1.
Now, the common factors can be found like this.
793:13x 61
686:2x 7x 7x 7
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 120223558/(1x13)
LCM = 120223558/13
LCM = 9247966
Thus, we can understand that the LCM of 793,686,221 is 9247966.
