Given numbers are 457,279,403,174,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 457,279,403,174,747 is 7979392746.
Find LCM of 457,279,403,174,747 with Prime Factorization
| 3 | 457, 279, 403, 174, 747 |
| 3 | 457, 93, 403, 58, 249 |
| 31 | 457, 31, 403, 58, 83 |
| 457, 1, 13, 58, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 31 x 457 x 1 x 13 x 58 x 83 = 7979392746
Therefore, the lowest common multiple of 457,279,403,174,747 is 7979392746.
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.
457 x 279 x 403 x 174 x 747 = 6678751728402
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.
457 : 1, 457
279 : 1, 3, 9, 31, 93, 279
403 : 1, 13, 31, 403
174 : 1, 2, 3, 6, 29, 58, 87, 174
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,279,403,174,747, is 1.
Now, the common factors can be found like this.
457:457
279:3x 3x 31
403:13x 31
174:2x 3x 29
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 31 = 837
Therefore, the value for common factors is 837.
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 = 6678751728402/(1x837)
LCM = 6678751728402/837
LCM = 7979392746
Thus, we can understand that the LCM of 457,279,403,174,747 is 7979392746.
