Given numbers are 172,970,962,676,916
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 172,970,962,676,916 is 119452184540.
Find LCM of 172,970,962,676,916 with Prime Factorization
| 2 | 172, 970, 962, 676, 916 |
| 2 | 86, 485, 481, 338, 458 |
| 13 | 43, 485, 481, 169, 229 |
| 43, 485, 37, 13, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 43 x 485 x 37 x 13 x 229 = 119452184540
Therefore, the lowest common multiple of 172,970,962,676,916 is 119452184540.
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.
172 x 970 x 962 x 676 x 916 = 99384217537280
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.
172 : 1, 2, 4, 43, 86, 172
970 : 1, 2, 5, 10, 97, 194, 485, 970
962 : 1, 2, 13, 26, 37, 74, 481, 962
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
916 : 1, 2, 4, 229, 458, 916
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,970,962,676,916, is 2.
Now, the common factors can be found like this.
172:2x 2x 43
970:2x 5x 97
962:2x 13x 37
676:2x 2x 13x 13
916:2x 2x 229
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 2x 2x 2x 13 = 416
Therefore, the value for common factors is 416.
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 = 99384217537280/(2x416)
LCM = 99384217537280/832
LCM = 119452184540
Thus, we can understand that the LCM of 172,970,962,676,916 is 119452184540.
