Given numbers are 967,663,221,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 967,663,221,686 is 439809006.
Find LCM of 967,663,221,686 with Prime Factorization
| 13 | 967, 663, 221, 686 |
| 17 | 967, 51, 17, 686 |
| 967, 3, 1, 686 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 967 x 3 x 1 x 686 = 439809006
Therefore, the lowest common multiple of 967,663,221,686 is 439809006.
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.
967 x 663 x 221 x 686 = 97197790326
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.
967 : 1, 967
663 : 1, 3, 13, 17, 39, 51, 221, 663
221 : 1, 13, 17, 221
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 967,663,221,686, is 1.
Now, the common factors can be found like this.
967:967
663:3x 13x 17
221:13x 17
686:2x 7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 97197790326/(1x221)
LCM = 97197790326/221
LCM = 439809006
Thus, we can understand that the LCM of 967,663,221,686 is 439809006.
