Given numbers are 853,640,561,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 853,640,561,946 is 13169228160.
Find LCM of 853,640,561,946 with Prime Factorization
| 2 | 853, 640, 561, 946 |
| 11 | 853, 320, 561, 473 |
| 853, 320, 51, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 853 x 320 x 51 x 43 = 13169228160
Therefore, the lowest common multiple of 853,640,561,946 is 13169228160.
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.
853 x 640 x 561 x 946 = 289723019520
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.
853 : 1, 853
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
561 : 1, 3, 11, 17, 33, 51, 187, 561
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,640,561,946, is 1.
Now, the common factors can be found like this.
853:853
640:2x 2x 2x 2x 2x 2x 2x 5
561:3x 11x 17
946:2x 11x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 289723019520/(1x22)
LCM = 289723019520/22
LCM = 13169228160
Thus, we can understand that the LCM of 853,640,561,946 is 13169228160.
