Given numbers are 691,779,988,469
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,779,988,469 is 13127792132.
Find LCM of 691,779,988,469 with Prime Factorization
19 | 691, 779, 988, 469 |
691, 41, 52, 469 |
Multiply the prime numbers at the bottom and the left side.
19 x 691 x 41 x 52 x 469 = 13127792132
Therefore, the lowest common multiple of 691,779,988,469 is 13127792132.
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.
691 x 779 x 988 x 469 = 249428050508
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.
691 : 1, 691
779 : 1, 19, 41, 779
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
469 : 1, 7, 67, 469
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,779,988,469, is 1.
Now, the common factors can be found like this.
691:691
779:19x 41
988:2x 2x 13x 19
469:7x 67
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 = 249428050508/(1x19)
LCM = 249428050508/19
LCM = 13127792132
Thus, we can understand that the LCM of 691,779,988,469 is 13127792132.
