Given numbers are 765,466,561,407,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 765,466,561,407,663 is 1886188590.
Find LCM of 765,466,561,407,663 with Prime Factorization
| 3 | 765, 466, 561, 407, 663 |
| 11 | 255, 466, 187, 407, 221 |
| 17 | 255, 466, 17, 37, 221 |
| 15, 466, 1, 37, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 15 x 466 x 1 x 37 x 13 = 1886188590
Therefore, the lowest common multiple of 765,466,561,407,663 is 1886188590.
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.
765 x 466 x 561 x 407 x 663 = 53965741748490
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
466 : 1, 2, 233, 466
561 : 1, 3, 11, 17, 33, 51, 187, 561
407 : 1, 11, 37, 407
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,466,561,407,663, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
466:2x 233
561:3x 11x 17
407:11x 37
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 17x 17 = 28611
Therefore, the value for common factors is 28611.
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 = 53965741748490/(1x28611)
LCM = 53965741748490/28611
LCM = 1886188590
Thus, we can understand that the LCM of 765,466,561,407,663 is 1886188590.
