Given numbers are 981,406,669,865,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,406,669,865,782 is 30039504786270.
Find LCM of 981,406,669,865,782 with Prime Factorization
2 | 981, 406, 669, 865, 782 |
3 | 981, 203, 669, 865, 391 |
327, 203, 223, 865, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 327 x 203 x 223 x 865 x 391 = 30039504786270
Therefore, the lowest common multiple of 981,406,669,865,782 is 30039504786270.
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.
981 x 406 x 669 x 865 x 782 = 180237028717620
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.
981 : 1, 3, 9, 109, 327, 981
406 : 1, 2, 7, 14, 29, 58, 203, 406
669 : 1, 3, 223, 669
865 : 1, 5, 173, 865
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,406,669,865,782, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
406:2x 7x 29
669:3x 223
865:5x 173
782:2x 17x 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 3 = 6
Therefore, the value for common factors is 6.
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 = 180237028717620/(1x6)
LCM = 180237028717620/6
LCM = 30039504786270
Thus, we can understand that the LCM of 981,406,669,865,782 is 30039504786270.
