Given numbers are 446,134,178,445,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 446,134,178,445,221 is 2938745290.
Find LCM of 446,134,178,445,221 with Prime Factorization
| 2 | 446, 134, 178, 445, 221 |
| 89 | 223, 67, 89, 445, 221 |
| 223, 67, 1, 5, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 89 x 223 x 67 x 1 x 5 x 221 = 2938745290
Therefore, the lowest common multiple of 446,134,178,445,221 is 2938745290.
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 134 x 178 x 445 x 221 = 1046193323240
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
134 : 1, 2, 67, 134
178 : 1, 2, 89, 178
445 : 1, 5, 89, 445
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 446,134,178,445,221, is 1.
Now, the common factors can be found like this.
446:2x 223
134:2x 67
178:2x 89
445:5x 89
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.
2x 2x 89 = 356
Therefore, the value for common factors is 356.
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 = 1046193323240/(1x356)
LCM = 1046193323240/356
LCM = 2938745290
Thus, we can understand that the LCM of 446,134,178,445,221 is 2938745290.
