Given numbers are 763,521,861,481,795
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 763,521,861,481,795 is 6232443110985.
Find LCM of 763,521,861,481,795 with Prime Factorization
| 3 | 763, 521, 861, 481, 795 |
| 7 | 763, 521, 287, 481, 265 |
| 109, 521, 41, 481, 265 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 109 x 521 x 41 x 481 x 265 = 6232443110985
Therefore, the lowest common multiple of 763,521,861,481,795 is 6232443110985.
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.
763 x 521 x 861 x 481 x 795 = 130881305330685
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.
763 : 1, 7, 109, 763
521 : 1, 521
861 : 1, 3, 7, 21, 41, 123, 287, 861
481 : 1, 13, 37, 481
795 : 1, 3, 5, 15, 53, 159, 265, 795
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,521,861,481,795, is 1.
Now, the common factors can be found like this.
763:7x 109
521:521
861:3x 7x 41
481:13x 37
795:3x 5x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 130881305330685/(1x21)
LCM = 130881305330685/21
LCM = 6232443110985
Thus, we can understand that the LCM of 763,521,861,481,795 is 6232443110985.
