Given numbers are 223,669,660,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 223,669,660,403 is 59313540.
Find LCM of 223,669,660,403 with Prime Factorization
| 3 | 223, 669, 660, 403 |
| 223 | 223, 223, 220, 403 |
| 1, 1, 220, 403 |
Multiply the prime numbers at the bottom and the left side.
3 x 223 x 1 x 1 x 220 x 403 = 59313540
Therefore, the lowest common multiple of 223,669,660,403 is 59313540.
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.
223 x 669 x 660 x 403 = 39680758260
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.
223 : 1, 223
669 : 1, 3, 223, 669
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
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,669,660,403, is 1.
Now, the common factors can be found like this.
223:223
669:3x 223
660:2x 2x 3x 5x 11
403:13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 223 = 669
Therefore, the value for common factors is 669.
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 = 39680758260/(1x669)
LCM = 39680758260/669
LCM = 59313540
Thus, we can understand that the LCM of 223,669,660,403 is 59313540.
