Given numbers are 665,551,979,517
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,551,979,517 is 887360705.
Find LCM of 665,551,979,517 with Prime Factorization
11 | 665, 551, 979, 517 |
19 | 665, 551, 89, 47 |
35, 29, 89, 47 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 35 x 29 x 89 x 47 = 887360705
Therefore, the lowest common multiple of 665,551,979,517 is 887360705.
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.
665 x 551 x 979 x 517 = 185458387345
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
551 : 1, 19, 29, 551
979 : 1, 11, 89, 979
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,551,979,517, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
551:19x 29
979:11x 89
517:11x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 19 = 209
Therefore, the value for common factors is 209.
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 = 185458387345/(1x209)
LCM = 185458387345/209
LCM = 887360705
Thus, we can understand that the LCM of 665,551,979,517 is 887360705.
