Given numbers are 782,618,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,618,422 is 50985618.
Find LCM of 782,618,422 with Prime Factorization
| 2 | 782, 618, 422 |
| 391, 309, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 391 x 309 x 211 = 50985618
Therefore, the lowest common multiple of 782,618,422 is 50985618.
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.
782 x 618 x 422 = 203942472
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
618 : 1, 2, 3, 6, 103, 206, 309, 618
422 : 1, 2, 211, 422
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,618,422, is 2.
Now, the common factors can be found like this.
782:2x 17x 23
618:2x 3x 103
422:2x 211
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 = 203942472/(2x2)
LCM = 203942472/4
LCM = 50985618
Thus, we can understand that the LCM of 782,618,422 is 50985618.
