Given numbers are 612,679,182,245,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 612,679,182,245,821 is 155230033140.
Find LCM of 612,679,182,245,821 with Prime Factorization
| 2 | 612, 679, 182, 245, 821 |
| 7 | 306, 679, 91, 245, 821 |
| 306, 97, 13, 35, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 306 x 97 x 13 x 35 x 821 = 155230033140
Therefore, the lowest common multiple of 612,679,182,245,821 is 155230033140.
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.
612 x 679 x 182 x 245 x 821 = 15212543247720
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
679 : 1, 7, 97, 679
182 : 1, 2, 7, 13, 14, 26, 91, 182
245 : 1, 5, 7, 35, 49, 245
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,679,182,245,821, is 1.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
679:7x 97
182:2x 7x 13
245:5x 7x 7
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7 = 98
Therefore, the value for common factors is 98.
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 = 15212543247720/(1x98)
LCM = 15212543247720/98
LCM = 155230033140
Thus, we can understand that the LCM of 612,679,182,245,821 is 155230033140.
