Given numbers are 640,531,218,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,531,218,779 is 28856154240.
Find LCM of 640,531,218,779 with Prime Factorization
2 | 640, 531, 218, 779 |
320, 531, 109, 779 |
Multiply the prime numbers at the bottom and the left side.
2 x 320 x 531 x 109 x 779 = 28856154240
Therefore, the lowest common multiple of 640,531,218,779 is 28856154240.
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.
640 x 531 x 218 x 779 = 57712308480
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
531 : 1, 3, 9, 59, 177, 531
218 : 1, 2, 109, 218
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,531,218,779, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
531:3x 3x 59
218:2x 109
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.
2 = 2
Therefore, the value for common factors is 2.
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 = 57712308480/(1x2)
LCM = 57712308480/2
LCM = 28856154240
Thus, we can understand that the LCM of 640,531,218,779 is 28856154240.
