Given numbers are 728,623,467,126
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 728,623,467,126 is 272320776.
Find LCM of 728,623,467,126 with Prime Factorization
| 2 | 728, 623, 467, 126 |
| 7 | 364, 623, 467, 63 |
| 52, 89, 467, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 52 x 89 x 467 x 9 = 272320776
Therefore, the lowest common multiple of 728,623,467,126 is 272320776.
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.
728 x 623 x 467 x 126 = 26687436048
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
623 : 1, 7, 89, 623
467 : 1, 467
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,623,467,126, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
623:7x 89
467:467
126:2x 3x 3x 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 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 = 26687436048/(1x98)
LCM = 26687436048/98
LCM = 272320776
Thus, we can understand that the LCM of 728,623,467,126 is 272320776.
