Given numbers are 676,288,847,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,288,847,505 is 20818717920.
Find LCM of 676,288,847,505 with Prime Factorization
2 | 676, 288, 847, 505 |
2 | 338, 144, 847, 505 |
169, 72, 847, 505 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 169 x 72 x 847 x 505 = 20818717920
Therefore, the lowest common multiple of 676,288,847,505 is 20818717920.
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.
676 x 288 x 847 x 505 = 83274871680
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
847 : 1, 7, 11, 77, 121, 847
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,288,847,505, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
288:2x 2x 2x 2x 2x 3x 3
847:7x 11x 11
505:5x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 83274871680/(1x4)
LCM = 83274871680/4
LCM = 20818717920
Thus, we can understand that the LCM of 676,288,847,505 is 20818717920.
