Given numbers are 611,200,654,138,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 611,200,654,138,981 is 2757198600.
Find LCM of 611,200,654,138,981 with Prime Factorization
| 2 | 611, 200, 654, 138, 981 |
| 3 | 611, 100, 327, 69, 981 |
| 109 | 611, 100, 109, 23, 327 |
| 611, 100, 1, 23, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 109 x 611 x 100 x 1 x 23 x 3 = 2757198600
Therefore, the lowest common multiple of 611,200,654,138,981 is 2757198600.
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.
611 x 200 x 654 x 138 x 981 = 10819247306400
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.
611 : 1, 13, 47, 611
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
654 : 1, 2, 3, 6, 109, 218, 327, 654
138 : 1, 2, 3, 6, 23, 46, 69, 138
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,200,654,138,981, is 1.
Now, the common factors can be found like this.
611:13x 47
200:2x 2x 2x 5x 5
654:2x 3x 109
138:2x 3x 23
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 109 = 3924
Therefore, the value for common factors is 3924.
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 = 10819247306400/(1x3924)
LCM = 10819247306400/3924
LCM = 2757198600
Thus, we can understand that the LCM of 611,200,654,138,981 is 2757198600.
