Given numbers are 639,243,925,175
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,243,925,175 is 111713175.
Find LCM of 639,243,925,175 with Prime Factorization
3 | 639, 243, 925, 175 |
3 | 213, 81, 925, 175 |
5 | 71, 27, 925, 175 |
5 | 71, 27, 185, 35 |
71, 27, 37, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 5 x 71 x 27 x 37 x 7 = 111713175
Therefore, the lowest common multiple of 639,243,925,175 is 111713175.
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.
639 x 243 x 925 x 175 = 25135464375
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.
639 : 1, 3, 9, 71, 213, 639
243 : 1, 3, 9, 27, 81, 243
925 : 1, 5, 25, 37, 185, 925
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,243,925,175, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
243:3x 3x 3x 3x 3
925:5x 5x 37
175:5x 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.
3x 3x 5x 5 = 225
Therefore, the value for common factors is 225.
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 = 25135464375/(1x225)
LCM = 25135464375/225
LCM = 111713175
Thus, we can understand that the LCM of 639,243,925,175 is 111713175.
