Given numbers are 775,676,715,525
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,676,715,525 is 121020900.
Find LCM of 775,676,715,525 with Prime Factorization
| 5 | 775, 676, 715, 525 |
| 5 | 155, 676, 143, 105 |
| 13 | 31, 676, 143, 21 |
| 31, 52, 11, 21 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 13 x 31 x 52 x 11 x 21 = 121020900
Therefore, the lowest common multiple of 775,676,715,525 is 121020900.
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.
775 x 676 x 715 x 525 = 196658962500
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.
775 : 1, 5, 25, 31, 155, 775
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
715 : 1, 5, 11, 13, 55, 65, 143, 715
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,676,715,525, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
676:2x 2x 13x 13
715:5x 11x 13
525:3x 5x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 5x 13 = 1625
Therefore, the value for common factors is 1625.
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 = 196658962500/(1x1625)
LCM = 196658962500/1625
LCM = 121020900
Thus, we can understand that the LCM of 775,676,715,525 is 121020900.
