Given numbers are 777,895,605,790,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,895,605,790,390 is 172834271610.
Find LCM of 777,895,605,790,390 with Prime Factorization
| 2 | 777, 895, 605, 790, 390 |
| 3 | 777, 895, 605, 395, 195 |
| 5 | 259, 895, 605, 395, 65 |
| 259, 179, 121, 79, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 259 x 179 x 121 x 79 x 13 = 172834271610
Therefore, the lowest common multiple of 777,895,605,790,390 is 172834271610.
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.
777 x 895 x 605 x 790 x 390 = 129625703707500
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
895 : 1, 5, 179, 895
605 : 1, 5, 11, 55, 121, 605
790 : 1, 2, 5, 10, 79, 158, 395, 790
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,895,605,790,390, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
895:5x 179
605:5x 11x 11
790:2x 5x 79
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 5 = 750
Therefore, the value for common factors is 750.
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 = 129625703707500/(1x750)
LCM = 129625703707500/750
LCM = 172834271610
Thus, we can understand that the LCM of 777,895,605,790,390 is 172834271610.
