Given numbers are 781,217,707,450,109
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,217,707,450,109 is 839597531850.
Find LCM of 781,217,707,450,109 with Prime Factorization
7 | 781, 217, 707, 450, 109 |
781, 31, 101, 450, 109 |
Multiply the prime numbers at the bottom and the left side.
7 x 781 x 31 x 101 x 450 x 109 = 839597531850
Therefore, the lowest common multiple of 781,217,707,450,109 is 839597531850.
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.
781 x 217 x 707 x 450 x 109 = 5877182722950
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.
781 : 1, 11, 71, 781
217 : 1, 7, 31, 217
707 : 1, 7, 101, 707
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,217,707,450,109, is 1.
Now, the common factors can be found like this.
781:11x 71
217:7x 31
707:7x 101
450:2x 3x 3x 5x 5
109:109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 5877182722950/(1x7)
LCM = 5877182722950/7
LCM = 839597531850
Thus, we can understand that the LCM of 781,217,707,450,109 is 839597531850.
