Given numbers are 671,695,517,163,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,695,517,163,660 is 42872028540.
Find LCM of 671,695,517,163,660 with Prime Factorization
| 5 | 671, 695, 517, 163, 660 |
| 11 | 671, 139, 517, 163, 132 |
| 61, 139, 47, 163, 12 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 61 x 139 x 47 x 163 x 12 = 42872028540
Therefore, the lowest common multiple of 671,695,517,163,660 is 42872028540.
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.
671 x 695 x 517 x 163 x 660 = 25937577266700
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.
671 : 1, 11, 61, 671
695 : 1, 5, 139, 695
517 : 1, 11, 47, 517
163 : 1, 163
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,695,517,163,660, is 1.
Now, the common factors can be found like this.
671:11x 61
695:5x 139
517:11x 47
163:163
660:2x 2x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 11 = 605
Therefore, the value for common factors is 605.
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 = 25937577266700/(1x605)
LCM = 25937577266700/605
LCM = 42872028540
Thus, we can understand that the LCM of 671,695,517,163,660 is 42872028540.
