Given numbers are 777,169,923,802,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,169,923,802,390 is 37386124230.
Find LCM of 777,169,923,802,390 with Prime Factorization
| 2 | 777, 169, 923, 802, 390 |
| 3 | 777, 169, 923, 401, 195 |
| 13 | 259, 169, 923, 401, 65 |
| 259, 13, 71, 401, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 259 x 13 x 71 x 401 x 5 = 37386124230
Therefore, the lowest common multiple of 777,169,923,802,390 is 37386124230.
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 169 x 923 x 802 x 390 = 37909529969220
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
169 : 1, 13, 169
923 : 1, 13, 71, 923
802 : 1, 2, 401, 802
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 777,169,923,802,390, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
169:13x 13
923:13x 71
802:2x 401
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 13x 13 = 1014
Therefore, the value for common factors is 1014.
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 = 37909529969220/(1x1014)
LCM = 37909529969220/1014
LCM = 37386124230
Thus, we can understand that the LCM of 777,169,923,802,390 is 37386124230.
