Given numbers are 672,447,147,159,531
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,447,147,159,531 is 6575105376.
Find LCM of 672,447,147,159,531 with Prime Factorization
| 3 | 672, 447, 147, 159, 531 |
| 7 | 224, 149, 49, 53, 177 |
| 32, 149, 7, 53, 177 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 32 x 149 x 7 x 53 x 177 = 6575105376
Therefore, the lowest common multiple of 672,447,147,159,531 is 6575105376.
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.
672 x 447 x 147 x 159 x 531 = 3728084748192
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.
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
447 : 1, 3, 149, 447
147 : 1, 3, 7, 21, 49, 147
159 : 1, 3, 53, 159
531 : 1, 3, 9, 59, 177, 531
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,447,147,159,531, is 3.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
447:3x 149
147:3x 7x 7
159:3x 53
531:3x 3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 3728084748192/(3x189)
LCM = 3728084748192/567
LCM = 6575105376
Thus, we can understand that the LCM of 672,447,147,159,531 is 6575105376.
