Given numbers are 515,625,865,175
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,625,865,175 is 77958125.
Find LCM of 515,625,865,175 with Prime Factorization
5 | 515, 625, 865, 175 |
5 | 103, 125, 173, 35 |
103, 25, 173, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 103 x 25 x 173 x 7 = 77958125
Therefore, the lowest common multiple of 515,625,865,175 is 77958125.
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.
515 x 625 x 865 x 175 = 48723828125
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.
515 : 1, 5, 103, 515
625 : 1, 5, 25, 125, 625
865 : 1, 5, 173, 865
175 : 1, 5, 7, 25, 35, 175
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,625,865,175, is 5.
Now, the common factors can be found like this.
515:5x 103
625:5x 5x 5x 5
865:5x 173
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.
5x 5x 5 = 125
Therefore, the value for common factors is 125.
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 = 48723828125/(5x125)
LCM = 48723828125/625
LCM = 77958125
Thus, we can understand that the LCM of 515,625,865,175 is 77958125.
