Given numbers are 725,989,145,160
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 725,989,145,160 is 22944800.
Find LCM of 725,989,145,160 with Prime Factorization
5 | 725, 989, 145, 160 |
29 | 145, 989, 29, 32 |
5, 989, 1, 32 |
Multiply the prime numbers at the bottom and the left side.
5 x 29 x 5 x 989 x 1 x 32 = 22944800
Therefore, the lowest common multiple of 725,989,145,160 is 22944800.
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.
725 x 989 x 145 x 160 = 16634980000
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.
725 : 1, 5, 25, 29, 145, 725
989 : 1, 23, 43, 989
145 : 1, 5, 29, 145
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,989,145,160, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
989:23x 43
145:5x 29
160:2x 2x 2x 2x 2x 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 29 = 725
Therefore, the value for common factors is 725.
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 = 16634980000/(1x725)
LCM = 16634980000/725
LCM = 22944800
Thus, we can understand that the LCM of 725,989,145,160 is 22944800.
