Given numbers are 985,788,479,456,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,788,479,456,478 is 51420285960.
Find LCM of 985,788,479,456,478 with Prime Factorization
| 2 | 985, 788, 479, 456, 478 |
| 2 | 985, 394, 479, 228, 239 |
| 197 | 985, 197, 479, 114, 239 |
| 5, 1, 479, 114, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 197 x 5 x 1 x 479 x 114 x 239 = 51420285960
Therefore, the lowest common multiple of 985,788,479,456,478 is 51420285960.
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.
985 x 788 x 479 x 456 x 478 = 81038370672960
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.
985 : 1, 5, 197, 985
788 : 1, 2, 4, 197, 394, 788
479 : 1, 479
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,788,479,456,478, is 1.
Now, the common factors can be found like this.
985:5x 197
788:2x 2x 197
479:479
456:2x 2x 2x 3x 19
478:2x 239
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 197 = 1576
Therefore, the value for common factors is 1576.
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 = 81038370672960/(1x1576)
LCM = 81038370672960/1576
LCM = 51420285960
Thus, we can understand that the LCM of 985,788,479,456,478 is 51420285960.
