Given numbers are 782,978,944,467,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,978,944,467,210 is 2950139386320.
Find LCM of 782,978,944,467,210 with Prime Factorization
| 2 | 782, 978, 944, 467, 210 |
| 3 | 391, 489, 472, 467, 105 |
| 391, 163, 472, 467, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 391 x 163 x 472 x 467 x 35 = 2950139386320
Therefore, the lowest common multiple of 782,978,944,467,210 is 2950139386320.
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.
782 x 978 x 944 x 467 x 210 = 70803345271680
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
978 : 1, 2, 3, 6, 163, 326, 489, 978
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
467 : 1, 467
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,978,944,467,210, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
978:2x 3x 163
944:2x 2x 2x 2x 59
467:467
210:2x 3x 5x 7
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 70803345271680/(1x24)
LCM = 70803345271680/24
LCM = 2950139386320
Thus, we can understand that the LCM of 782,978,944,467,210 is 2950139386320.
