Given numbers are 790,817,691,946,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,817,691,946,923 is 4528158095890.
Find LCM of 790,817,691,946,923 with Prime Factorization
| 2 | 790, 817, 691, 946, 923 |
| 43 | 395, 817, 691, 473, 923 |
| 395, 19, 691, 11, 923 |
Multiply the prime numbers at the bottom and the left side.
2 x 43 x 395 x 19 x 691 x 11 x 923 = 4528158095890
Therefore, the lowest common multiple of 790,817,691,946,923 is 4528158095890.
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.
790 x 817 x 691 x 946 x 923 = 389421596246540
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
817 : 1, 19, 43, 817
691 : 1, 691
946 : 1, 2, 11, 22, 43, 86, 473, 946
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,817,691,946,923, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
817:19x 43
691:691
946:2x 11x 43
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 43 = 86
Therefore, the value for common factors is 86.
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 = 389421596246540/(1x86)
LCM = 389421596246540/86
LCM = 4528158095890
Thus, we can understand that the LCM of 790,817,691,946,923 is 4528158095890.
