Given numbers are 817,402,779,527,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,402,779,527,561 is 78061207818.
Find LCM of 817,402,779,527,561 with Prime Factorization
3 | 817, 402, 779, 527, 561 |
17 | 817, 134, 779, 527, 187 |
19 | 817, 134, 779, 31, 11 |
43, 134, 41, 31, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 19 x 43 x 134 x 41 x 31 x 11 = 78061207818
Therefore, the lowest common multiple of 817,402,779,527,561 is 78061207818.
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.
817 x 402 x 779 x 527 x 561 = 75641310375642
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.
817 : 1, 19, 43, 817
402 : 1, 2, 3, 6, 67, 134, 201, 402
779 : 1, 19, 41, 779
527 : 1, 17, 31, 527
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 817,402,779,527,561, is 1.
Now, the common factors can be found like this.
817:19x 43
402:2x 3x 67
779:19x 41
527:17x 31
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.
3x 17x 19 = 969
Therefore, the value for common factors is 969.
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 = 75641310375642/(1x969)
LCM = 75641310375642/969
LCM = 78061207818
Thus, we can understand that the LCM of 817,402,779,527,561 is 78061207818.
