Given numbers are 476,663,778,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 476,663,778,561 is 79435356.
Find LCM of 476,663,778,561 with Prime Factorization
| 2 | 476, 663, 778, 561 |
| 3 | 238, 663, 389, 561 |
| 17 | 238, 221, 389, 187 |
| 14, 13, 389, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 14 x 13 x 389 x 11 = 79435356
Therefore, the lowest common multiple of 476,663,778,561 is 79435356.
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.
476 x 663 x 778 x 561 = 137740907304
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
663 : 1, 3, 13, 17, 39, 51, 221, 663
778 : 1, 2, 389, 778
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,663,778,561, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
663:3x 13x 17
778:2x 389
561:3x 11x 17
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 17x 17 = 1734
Therefore, the value for common factors is 1734.
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 = 137740907304/(1x1734)
LCM = 137740907304/1734
LCM = 79435356
Thus, we can understand that the LCM of 476,663,778,561 is 79435356.
