Given numbers are 218,445,447,356,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,445,447,356,738 is 10667413620.
Find LCM of 218,445,447,356,738 with Prime Factorization
| 2 | 218, 445, 447, 356, 738 |
| 3 | 109, 445, 447, 178, 369 |
| 89 | 109, 445, 149, 178, 123 |
| 109, 5, 149, 2, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 89 x 109 x 5 x 149 x 2 x 123 = 10667413620
Therefore, the lowest common multiple of 218,445,447,356,738 is 10667413620.
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.
218 x 445 x 447 x 356 x 738 = 11392797746160
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.
218 : 1, 2, 109, 218
445 : 1, 5, 89, 445
447 : 1, 3, 149, 447
356 : 1, 2, 4, 89, 178, 356
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,445,447,356,738, is 1.
Now, the common factors can be found like this.
218:2x 109
445:5x 89
447:3x 149
356:2x 2x 89
738:2x 3x 3x 41
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 3x 89 = 1068
Therefore, the value for common factors is 1068.
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 = 11392797746160/(1x1068)
LCM = 11392797746160/1068
LCM = 10667413620
Thus, we can understand that the LCM of 218,445,447,356,738 is 10667413620.
