Given numbers are 194,728,742,126
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 194,728,742,126 is 33683832.
Find LCM of 194,728,742,126 with Prime Factorization
| 2 | 194, 728, 742, 126 |
| 7 | 97, 364, 371, 63 |
| 97, 52, 53, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 97 x 52 x 53 x 9 = 33683832
Therefore, the lowest common multiple of 194,728,742,126 is 33683832.
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.
194 x 728 x 742 x 126 = 13204062144
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.
194 : 1, 2, 97, 194
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
742 : 1, 2, 7, 14, 53, 106, 371, 742
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,728,742,126, is 2.
Now, the common factors can be found like this.
194:2x 97
728:2x 2x 2x 7x 13
742:2x 7x 53
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 2x 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 13204062144/(2x196)
LCM = 13204062144/392
LCM = 33683832
Thus, we can understand that the LCM of 194,728,742,126 is 33683832.
