Given numbers are 145,646,361,649,531
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 145,646,361,649,531 is 10395402930.
Find LCM of 145,646,361,649,531 with Prime Factorization
| 19 | 145, 646, 361, 649, 531 |
| 59 | 145, 34, 19, 649, 531 |
| 145, 34, 19, 11, 9 |
Multiply the prime numbers at the bottom and the left side.
19 x 59 x 145 x 34 x 19 x 11 x 9 = 10395402930
Therefore, the lowest common multiple of 145,646,361,649,531 is 10395402930.
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.
145 x 646 x 361 x 649 x 531 = 11653246684530
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.
145 : 1, 5, 29, 145
646 : 1, 2, 17, 19, 34, 38, 323, 646
361 : 1, 19, 361
649 : 1, 11, 59, 649
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 145,646,361,649,531, is 1.
Now, the common factors can be found like this.
145:5x 29
646:2x 17x 19
361:19x 19
649:11x 59
531:3x 3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 59 = 1121
Therefore, the value for common factors is 1121.
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 = 11653246684530/(1x1121)
LCM = 11653246684530/1121
LCM = 10395402930
Thus, we can understand that the LCM of 145,646,361,649,531 is 10395402930.
