Given numbers are 775,210,371,765,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,210,371,765,815 is 14341171950.
Find LCM of 775,210,371,765,815 with Prime Factorization
| 3 | 775, 210, 371, 765, 815 |
| 5 | 775, 70, 371, 255, 815 |
| 7 | 155, 14, 371, 51, 163 |
| 155, 2, 53, 51, 163 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 155 x 2 x 53 x 51 x 163 = 14341171950
Therefore, the lowest common multiple of 775,210,371,765,815 is 14341171950.
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.
775 x 210 x 371 x 765 x 815 = 37645576368750
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.
775 : 1, 5, 25, 31, 155, 775
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
371 : 1, 7, 53, 371
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,210,371,765,815, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
210:2x 3x 5x 7
371:7x 53
765:3x 3x 5x 17
815:5x 163
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 5x 5x 7 = 2625
Therefore, the value for common factors is 2625.
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 = 37645576368750/(1x2625)
LCM = 37645576368750/2625
LCM = 14341171950
Thus, we can understand that the LCM of 775,210,371,765,815 is 14341171950.
