Given numbers are 817,771,871,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,771,871,923 is 38954078787.
Find LCM of 817,771,871,923 with Prime Factorization
13 | 817, 771, 871, 923 |
817, 771, 67, 71 |
Multiply the prime numbers at the bottom and the left side.
13 x 817 x 771 x 67 x 71 = 38954078787
Therefore, the lowest common multiple of 817,771,871,923 is 38954078787.
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 771 x 871 x 923 = 506403024231
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
771 : 1, 3, 257, 771
871 : 1, 13, 67, 871
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,771,871,923, is 1.
Now, the common factors can be found like this.
817:19x 43
771:3x 257
871:13x 67
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 506403024231/(1x13)
LCM = 506403024231/13
LCM = 38954078787
Thus, we can understand that the LCM of 817,771,871,923 is 38954078787.
