Given numbers are 3,985,281,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 3,985,281,680 is 112928280.
Find LCM of 3,985,281,680 with Prime Factorization
| 5 | 3, 985, 281, 680 |
| 3, 197, 281, 136 |
Multiply the prime numbers at the bottom and the left side.
5 x 3 x 197 x 281 x 136 = 112928280
Therefore, the lowest common multiple of 3,985,281,680 is 112928280.
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.
3 x 985 x 281 x 680 = 564641400
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.
3 : 1, 3
985 : 1, 5, 197, 985
281 : 1, 281
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3,985,281,680, is 1.
Now, the common factors can be found like this.
3:3
985:5x 197
281:281
680:2x 2x 2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 564641400/(1x5)
LCM = 564641400/5
LCM = 112928280
Thus, we can understand that the LCM of 3,985,281,680 is 112928280.
