Given numbers are 689,949,818,611,417
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,949,818,611,417 is 806360598654.
Find LCM of 689,949,818,611,417 with Prime Factorization
| 13 | 689, 949, 818, 611, 417 |
| 53, 73, 818, 47, 417 |
Multiply the prime numbers at the bottom and the left side.
13 x 53 x 73 x 818 x 47 x 417 = 806360598654
Therefore, the lowest common multiple of 689,949,818,611,417 is 806360598654.
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.
689 x 949 x 818 x 611 x 417 = 136274941172526
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.
689 : 1, 13, 53, 689
949 : 1, 13, 73, 949
818 : 1, 2, 409, 818
611 : 1, 13, 47, 611
417 : 1, 3, 139, 417
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,949,818,611,417, is 1.
Now, the common factors can be found like this.
689:13x 53
949:13x 73
818:2x 409
611:13x 47
417:3x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13 = 169
Therefore, the value for common factors is 169.
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 = 136274941172526/(1x169)
LCM = 136274941172526/169
LCM = 806360598654
Thus, we can understand that the LCM of 689,949,818,611,417 is 806360598654.
