Given numbers are 869,865,798,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,865,798,779 is 24593629830.
Find LCM of 869,865,798,779 with Prime Factorization
19 | 869, 865, 798, 779 |
869, 865, 42, 41 |
Multiply the prime numbers at the bottom and the left side.
19 x 869 x 865 x 42 x 41 = 24593629830
Therefore, the lowest common multiple of 869,865,798,779 is 24593629830.
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.
869 x 865 x 798 x 779 = 467278966770
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.
869 : 1, 11, 79, 869
865 : 1, 5, 173, 865
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,865,798,779, is 1.
Now, the common factors can be found like this.
869:11x 79
865:5x 173
798:2x 3x 7x 19
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 467278966770/(1x19)
LCM = 467278966770/19
LCM = 24593629830
Thus, we can understand that the LCM of 869,865,798,779 is 24593629830.
