Given numbers are 766,263,580,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,263,580,638 is 642651020.
Find LCM of 766,263,580,638 with Prime Factorization
| 2 | 766, 263, 580, 638 |
| 29 | 383, 263, 290, 319 |
| 383, 263, 10, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 383 x 263 x 10 x 11 = 642651020
Therefore, the lowest common multiple of 766,263,580,638 is 642651020.
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.
766 x 263 x 580 x 638 = 74547518320
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.
766 : 1, 2, 383, 766
263 : 1, 263
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,263,580,638, is 1.
Now, the common factors can be found like this.
766:2x 383
263:263
580:2x 2x 5x 29
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 29 = 116
Therefore, the value for common factors is 116.
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 = 74547518320/(1x116)
LCM = 74547518320/116
LCM = 642651020
Thus, we can understand that the LCM of 766,263,580,638 is 642651020.
