Given numbers are 699,646,640,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,646,640,389 is 56209441920.
Find LCM of 699,646,640,389 with Prime Factorization
2 | 699, 646, 640, 389 |
699, 323, 320, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 699 x 323 x 320 x 389 = 56209441920
Therefore, the lowest common multiple of 699,646,640,389 is 56209441920.
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.
699 x 646 x 640 x 389 = 112418883840
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.
699 : 1, 3, 233, 699
646 : 1, 2, 17, 19, 34, 38, 323, 646
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,646,640,389, is 1.
Now, the common factors can be found like this.
699:3x 233
646:2x 17x 19
640:2x 2x 2x 2x 2x 2x 2x 5
389:389
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 = 112418883840/(1x2)
LCM = 112418883840/2
LCM = 56209441920
Thus, we can understand that the LCM of 699,646,640,389 is 56209441920.
