Given numbers are 665,998,451,485
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,998,451,485 is 29033571490.
Find LCM of 665,998,451,485 with Prime Factorization
| 5 | 665, 998, 451, 485 |
| 133, 998, 451, 97 |
Multiply the prime numbers at the bottom and the left side.
5 x 133 x 998 x 451 x 97 = 29033571490
Therefore, the lowest common multiple of 665,998,451,485 is 29033571490.
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.
665 x 998 x 451 x 485 = 145167857450
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
998 : 1, 2, 499, 998
451 : 1, 11, 41, 451
485 : 1, 5, 97, 485
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,998,451,485, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
998:2x 499
451:11x 41
485:5x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 145167857450/(1x5)
LCM = 145167857450/5
LCM = 29033571490
Thus, we can understand that the LCM of 665,998,451,485 is 29033571490.
