Given numbers are 981,302,597,420,347
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,302,597,420,347 is 1432044592020.
Find LCM of 981,302,597,420,347 with Prime Factorization
| 2 | 981, 302, 597, 420, 347 |
| 3 | 981, 151, 597, 210, 347 |
| 327, 151, 199, 70, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 327 x 151 x 199 x 70 x 347 = 1432044592020
Therefore, the lowest common multiple of 981,302,597,420,347 is 1432044592020.
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 302 x 597 x 420 x 347 = 25776802656360
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
302 : 1, 2, 151, 302
597 : 1, 3, 199, 597
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
347 : 1, 347
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,302,597,420,347, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
302:2x 151
597:3x 199
420:2x 2x 3x 5x 7
347:347
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 25776802656360/(1x18)
LCM = 25776802656360/18
LCM = 1432044592020
Thus, we can understand that the LCM of 981,302,597,420,347 is 1432044592020.
