Given numbers are 271,442,988,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 271,442,988,639 is 2908546524.
Find LCM of 271,442,988,639 with Prime Factorization
2 | 271, 442, 988, 639 |
13 | 271, 221, 494, 639 |
271, 17, 38, 639 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 271 x 17 x 38 x 639 = 2908546524
Therefore, the lowest common multiple of 271,442,988,639 is 2908546524.
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.
271 x 442 x 988 x 639 = 75622209624
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.
271 : 1, 271
442 : 1, 2, 13, 17, 26, 34, 221, 442
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 271,442,988,639, is 1.
Now, the common factors can be found like this.
271:271
442:2x 13x 17
988:2x 2x 13x 19
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 75622209624/(1x26)
LCM = 75622209624/26
LCM = 2908546524
Thus, we can understand that the LCM of 271,442,988,639 is 2908546524.
