Given numbers are 852,651,690,943
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 852,651,690,943 is 871728060.
Find LCM of 852,651,690,943 with Prime Factorization
2 | 852, 651, 690, 943 |
3 | 426, 651, 345, 943 |
23 | 142, 217, 115, 943 |
142, 217, 5, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 142 x 217 x 5 x 41 = 871728060
Therefore, the lowest common multiple of 852,651,690,943 is 871728060.
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.
852 x 651 x 690 x 943 = 360895416840
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.
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
651 : 1, 3, 7, 21, 31, 93, 217, 651
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 852,651,690,943, is 1.
Now, the common factors can be found like this.
852:2x 2x 3x 71
651:3x 7x 31
690:2x 3x 5x 23
943:23x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 23 = 414
Therefore, the value for common factors is 414.
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 = 360895416840/(1x414)
LCM = 360895416840/414
LCM = 871728060
Thus, we can understand that the LCM of 852,651,690,943 is 871728060.
