Find LCM of 989,920,397,625,625 with Prime Factorization
5 | 989, 920, 397, 625, 625 |
5 | 989, 184, 397, 125, 125 |
5 | 989, 184, 397, 25, 25 |
5 | 989, 184, 397, 5, 5 |
23 | 989, 184, 397, 1, 1 |
43, 8, 397, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 5 x 5 x 23 x 43 x 8 x 397 x 1 x 1 = 1963165000
Therefore, the lowest common multiple of 989,920,397,625,625 is 1963165000.
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.
989 x 920 x 397 x 625 x 625 = 141102484375000
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.
989 : 1, 23, 43, 989
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
397 : 1, 397
625 : 1, 5, 25, 125, 625
625 : 1, 5, 25, 125, 625
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,920,397,625,625, is 1.
Now, the common factors can be found like this.
989:23x 43
920:2x 2x 2x 5x 23
397:397
625:5x 5x 5x 5
625:5x 5x 5x 5
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 5x 5x 23 = 71875
Therefore, the value for common factors is 71875.
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 = 141102484375000/(1x71875)
LCM = 141102484375000/71875
LCM = 1963165000
Thus, we can understand that the LCM of 989,920,397,625,625 is 1963165000.
