Given numbers are 676,391,939,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,391,939,434 is 53857821108.
Find LCM of 676,391,939,434 with Prime Factorization
2 | 676, 391, 939, 434 |
338, 391, 939, 217 |
Multiply the prime numbers at the bottom and the left side.
2 x 338 x 391 x 939 x 217 = 53857821108
Therefore, the lowest common multiple of 676,391,939,434 is 53857821108.
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.
676 x 391 x 939 x 434 = 107715642216
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
391 : 1, 17, 23, 391
939 : 1, 3, 313, 939
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,391,939,434, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
391:17x 23
939:3x 313
434:2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 107715642216/(1x2)
LCM = 107715642216/2
LCM = 53857821108
Thus, we can understand that the LCM of 676,391,939,434 is 53857821108.
