Given numbers are 790,446,394,865
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,446,394,865 is 6004049770.
Find LCM of 790,446,394,865 with Prime Factorization
2 | 790, 446, 394, 865 |
5 | 395, 223, 197, 865 |
79, 223, 197, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 79 x 223 x 197 x 173 = 6004049770
Therefore, the lowest common multiple of 790,446,394,865 is 6004049770.
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 446 x 394 x 865 = 120080995400
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
446 : 1, 2, 223, 446
394 : 1, 2, 197, 394
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,446,394,865, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
446:2x 223
394:2x 197
865:5x 173
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 5 = 20
Therefore, the value for common factors is 20.
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 = 120080995400/(1x20)
LCM = 120080995400/20
LCM = 6004049770
Thus, we can understand that the LCM of 790,446,394,865 is 6004049770.
