Given numbers are 487,765,129,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,765,129,817 is 304377435.
Find LCM of 487,765,129,817 with Prime Factorization
3 | 487, 765, 129, 817 |
43 | 487, 255, 43, 817 |
487, 255, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 487 x 255 x 1 x 19 = 304377435
Therefore, the lowest common multiple of 487,765,129,817 is 304377435.
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.
487 x 765 x 129 x 817 = 39264689115
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.
487 : 1, 487
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
129 : 1, 3, 43, 129
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,765,129,817, is 1.
Now, the common factors can be found like this.
487:487
765:3x 3x 5x 17
129:3x 43
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 39264689115/(1x129)
LCM = 39264689115/129
LCM = 304377435
Thus, we can understand that the LCM of 487,765,129,817 is 304377435.
