Given numbers are 665,712,798,769,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,712,798,769,874 is 25123322280.
Find LCM of 665,712,798,769,874 with Prime Factorization
| 2 | 665, 712, 798, 769, 874 |
| 7 | 665, 356, 399, 769, 437 |
| 19 | 95, 356, 57, 769, 437 |
| 5, 356, 3, 769, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 5 x 356 x 3 x 769 x 23 = 25123322280
Therefore, the lowest common multiple of 665,712,798,769,874 is 25123322280.
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.
665 x 712 x 798 x 769 x 874 = 253946541606240
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
712 : 1, 2, 4, 8, 89, 178, 356, 712
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
769 : 1, 769
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,712,798,769,874, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
712:2x 2x 2x 89
798:2x 3x 7x 19
769:769
874:2x 19x 23
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 7x 19x 19 = 10108
Therefore, the value for common factors is 10108.
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 = 253946541606240/(1x10108)
LCM = 253946541606240/10108
LCM = 25123322280
Thus, we can understand that the LCM of 665,712,798,769,874 is 25123322280.
