Given numbers are 687,740,779,575
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,740,779,575 is 45543222300.
Find LCM of 687,740,779,575 with Prime Factorization
5 | 687, 740, 779, 575 |
687, 148, 779, 115 |
Multiply the prime numbers at the bottom and the left side.
5 x 687 x 148 x 779 x 115 = 45543222300
Therefore, the lowest common multiple of 687,740,779,575 is 45543222300.
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.
687 x 740 x 779 x 575 = 227716111500
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.
687 : 1, 3, 229, 687
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
779 : 1, 19, 41, 779
575 : 1, 5, 23, 25, 115, 575
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,740,779,575, is 1.
Now, the common factors can be found like this.
687:3x 229
740:2x 2x 5x 37
779:19x 41
575:5x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 227716111500/(1x5)
LCM = 227716111500/5
LCM = 45543222300
Thus, we can understand that the LCM of 687,740,779,575 is 45543222300.
