Given numbers are 639,501,653,654,485
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,501,653,654,485 is 7367645864970.
Find LCM of 639,501,653,654,485 with Prime Factorization
| 3 | 639, 501, 653, 654, 485 |
| 213, 167, 653, 218, 485 |
Multiply the prime numbers at the bottom and the left side.
3 x 213 x 167 x 653 x 218 x 485 = 7367645864970
Therefore, the lowest common multiple of 639,501,653,654,485 is 7367645864970.
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.
639 x 501 x 653 x 654 x 485 = 66308812784730
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.
639 : 1, 3, 9, 71, 213, 639
501 : 1, 3, 167, 501
653 : 1, 653
654 : 1, 2, 3, 6, 109, 218, 327, 654
485 : 1, 5, 97, 485
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,501,653,654,485, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
501:3x 167
653:653
654:2x 3x 109
485:5x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 66308812784730/(1x9)
LCM = 66308812784730/9
LCM = 7367645864970
Thus, we can understand that the LCM of 639,501,653,654,485 is 7367645864970.
