Given numbers are 137,278,417,427,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 137,278,417,427,643 is 31370790738.
Find LCM of 137,278,417,427,643 with Prime Factorization
| 139 | 137, 278, 417, 427, 643 |
| 137, 2, 3, 427, 643 |
Multiply the prime numbers at the bottom and the left side.
139 x 137 x 2 x 3 x 427 x 643 = 31370790738
Therefore, the lowest common multiple of 137,278,417,427,643 is 31370790738.
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.
137 x 278 x 417 x 427 x 643 = 4360539912582
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.
137 : 1, 137
278 : 1, 2, 139, 278
417 : 1, 3, 139, 417
427 : 1, 7, 61, 427
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,278,417,427,643, is 1.
Now, the common factors can be found like this.
137:137
278:2x 139
417:3x 139
427:7x 61
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
139 = 139
Therefore, the value for common factors is 139.
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 = 4360539912582/(1x139)
LCM = 4360539912582/139
LCM = 31370790738
Thus, we can understand that the LCM of 137,278,417,427,643 is 31370790738.
