Given numbers are 446,634,266,21
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 446,634,266,21 is 56411418.
Find LCM of 446,634,266,21 with Prime Factorization
| 2 | 446, 634, 266, 21 |
| 7 | 223, 317, 133, 21 |
| 223, 317, 19, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 223 x 317 x 19 x 3 = 56411418
Therefore, the lowest common multiple of 446,634,266,21 is 56411418.
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.
446 x 634 x 266 x 21 = 1579519704
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.
446 : 1, 2, 223, 446
634 : 1, 2, 317, 634
266 : 1, 2, 7, 14, 19, 38, 133, 266
21 : 1, 3, 7, 21
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 446,634,266,21, is 1.
Now, the common factors can be found like this.
446:2x 223
634:2x 317
266:2x 7x 19
21:3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7 = 28
Therefore, the value for common factors is 28.
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 = 1579519704/(1x28)
LCM = 1579519704/28
LCM = 56411418
Thus, we can understand that the LCM of 446,634,266,21 is 56411418.
