Given numbers are 991,946,338,368
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,946,338,368 is 29152064656.
Find LCM of 991,946,338,368 with Prime Factorization
| 2 | 991, 946, 338, 368 |
| 991, 473, 169, 184 |
Multiply the prime numbers at the bottom and the left side.
2 x 991 x 473 x 169 x 184 = 29152064656
Therefore, the lowest common multiple of 991,946,338,368 is 29152064656.
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.
991 x 946 x 338 x 368 = 116608258624
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.
991 : 1, 991
946 : 1, 2, 11, 22, 43, 86, 473, 946
338 : 1, 2, 13, 26, 169, 338
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,946,338,368, is 1.
Now, the common factors can be found like this.
991:991
946:2x 11x 43
338:2x 13x 13
368:2x 2x 2x 2x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 116608258624/(1x4)
LCM = 116608258624/4
LCM = 29152064656
Thus, we can understand that the LCM of 991,946,338,368 is 29152064656.
