Given numbers are 642,629,492,149
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,629,492,149 is 4933848324.
Find LCM of 642,629,492,149 with Prime Factorization
2 | 642, 629, 492, 149 |
3 | 321, 629, 246, 149 |
107, 629, 82, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 629 x 82 x 149 = 4933848324
Therefore, the lowest common multiple of 642,629,492,149 is 4933848324.
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.
642 x 629 x 492 x 149 = 29603089944
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
629 : 1, 17, 37, 629
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
149 : 1, 149
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,629,492,149, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
629:17x 37
492:2x 2x 3x 41
149:149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 29603089944/(1x6)
LCM = 29603089944/6
LCM = 4933848324
Thus, we can understand that the LCM of 642,629,492,149 is 4933848324.
