Given numbers are 137,403,611,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 137,403,611,961 is 80442427.
Find LCM of 137,403,611,961 with Prime Factorization
| 13 | 137, 403, 611, 961 |
| 31 | 137, 31, 47, 961 |
| 137, 1, 47, 31 |
Multiply the prime numbers at the bottom and the left side.
13 x 31 x 137 x 1 x 47 x 31 = 80442427
Therefore, the lowest common multiple of 137,403,611,961 is 80442427.
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 403 x 611 x 961 = 32418298081
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
403 : 1, 13, 31, 403
611 : 1, 13, 47, 611
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,403,611,961, is 1.
Now, the common factors can be found like this.
137:137
403:13x 31
611:13x 47
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 31 = 403
Therefore, the value for common factors is 403.
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 = 32418298081/(1x403)
LCM = 32418298081/403
LCM = 80442427
Thus, we can understand that the LCM of 137,403,611,961 is 80442427.
