Given numbers are 274,721,738,447,670
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 274,721,738,447,670 is 3638675018790.
Find LCM of 274,721,738,447,670 with Prime Factorization
2 | 274, 721, 738, 447, 670 |
3 | 137, 721, 369, 447, 335 |
137, 721, 123, 149, 335 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 137 x 721 x 123 x 149 x 335 = 3638675018790
Therefore, the lowest common multiple of 274,721,738,447,670 is 3638675018790.
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.
274 x 721 x 738 x 447 x 670 = 43664100225480
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.
274 : 1, 2, 137, 274
721 : 1, 7, 103, 721
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
447 : 1, 3, 149, 447
670 : 1, 2, 5, 10, 67, 134, 335, 670
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 274,721,738,447,670, is 1.
Now, the common factors can be found like this.
274:2x 137
721:7x 103
738:2x 3x 3x 41
447:3x 149
670:2x 5x 67
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 3 = 12
Therefore, the value for common factors is 12.
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 = 43664100225480/(1x12)
LCM = 43664100225480/12
LCM = 3638675018790
Thus, we can understand that the LCM of 274,721,738,447,670 is 3638675018790.
