Given numbers are 516,745,865,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 516,745,865,285 is 1263588540.
Find LCM of 516,745,865,285 with Prime Factorization
3 | 516, 745, 865, 285 |
5 | 172, 745, 865, 95 |
172, 149, 173, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 172 x 149 x 173 x 19 = 1263588540
Therefore, the lowest common multiple of 516,745,865,285 is 1263588540.
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.
516 x 745 x 865 x 285 = 94769140500
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.
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
745 : 1, 5, 149, 745
865 : 1, 5, 173, 865
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,745,865,285, is 1.
Now, the common factors can be found like this.
516:2x 2x 3x 43
745:5x 149
865:5x 173
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5 = 75
Therefore, the value for common factors is 75.
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 = 94769140500/(1x75)
LCM = 94769140500/75
LCM = 1263588540
Thus, we can understand that the LCM of 516,745,865,285 is 1263588540.
