Given numbers are 766,561,361,638,452
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,561,361,638,452 is 1016729137644.
Find LCM of 766,561,361,638,452 with Prime Factorization
| 2 | 766, 561, 361, 638, 452 |
| 11 | 383, 561, 361, 319, 226 |
| 383, 51, 361, 29, 226 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 383 x 51 x 361 x 29 x 226 = 1016729137644
Therefore, the lowest common multiple of 766,561,361,638,452 is 1016729137644.
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 561 x 361 x 638 x 452 = 44736082056336
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
561 : 1, 3, 11, 17, 33, 51, 187, 561
361 : 1, 19, 361
638 : 1, 2, 11, 22, 29, 58, 319, 638
452 : 1, 2, 4, 113, 226, 452
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,561,361,638,452, is 1.
Now, the common factors can be found like this.
766:2x 383
561:3x 11x 17
361:19x 19
638:2x 11x 29
452:2x 2x 113
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 11 = 44
Therefore, the value for common factors is 44.
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 = 44736082056336/(1x44)
LCM = 44736082056336/44
LCM = 1016729137644
Thus, we can understand that the LCM of 766,561,361,638,452 is 1016729137644.
