Given numbers are 775,961,453,558
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,961,453,558 is 65299950.
Find LCM of 775,961,453,558 with Prime Factorization
| 3 | 775, 961, 453, 558 |
| 31 | 775, 961, 151, 186 |
| 25, 31, 151, 6 |
Multiply the prime numbers at the bottom and the left side.
3 x 31 x 25 x 31 x 151 x 6 = 65299950
Therefore, the lowest common multiple of 775,961,453,558 is 65299950.
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 961 x 453 x 558 = 188259755850
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
961 : 1, 31, 961
453 : 1, 3, 151, 453
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,961,453,558, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
961:31x 31
453:3x 151
558:2x 3x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 31x 31 = 2883
Therefore, the value for common factors is 2883.
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 = 188259755850/(1x2883)
LCM = 188259755850/2883
LCM = 65299950
Thus, we can understand that the LCM of 775,961,453,558 is 65299950.
