Given numbers are 812,763,489,673,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,763,489,673,221 is 6437225517996.
Find LCM of 812,763,489,673,221 with Prime Factorization
| 7 | 812, 763, 489, 673, 221 |
| 116, 109, 489, 673, 221 |
Multiply the prime numbers at the bottom and the left side.
7 x 116 x 109 x 489 x 673 x 221 = 6437225517996
Therefore, the lowest common multiple of 812,763,489,673,221 is 6437225517996.
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.
812 x 763 x 489 x 673 x 221 = 45060578625972
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
763 : 1, 7, 109, 763
489 : 1, 3, 163, 489
673 : 1, 673
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,763,489,673,221, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
763:7x 109
489:3x 163
673:673
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 45060578625972/(1x7)
LCM = 45060578625972/7
LCM = 6437225517996
Thus, we can understand that the LCM of 812,763,489,673,221 is 6437225517996.
