Given numbers are 674,860,657,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 674,860,657,172 is 190411740.
Find LCM of 674,860,657,172 with Prime Factorization
| 2 | 674, 860, 657, 172 |
| 2 | 337, 430, 657, 86 |
| 43 | 337, 215, 657, 43 |
| 337, 5, 657, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 337 x 5 x 657 x 1 = 190411740
Therefore, the lowest common multiple of 674,860,657,172 is 190411740.
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.
674 x 860 x 657 x 172 = 65501638560
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.
674 : 1, 2, 337, 674
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
657 : 1, 3, 9, 73, 219, 657
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,860,657,172, is 1.
Now, the common factors can be found like this.
674:2x 337
860:2x 2x 5x 43
657:3x 3x 73
172:2x 2x 43
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 43 = 344
Therefore, the value for common factors is 344.
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 = 65501638560/(1x344)
LCM = 65501638560/344
LCM = 190411740
Thus, we can understand that the LCM of 674,860,657,172 is 190411740.
