Given numbers are 634,465,589,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,465,589,257 is 1439557230.
Find LCM of 634,465,589,257 with Prime Factorization
31 | 634, 465, 589, 257 |
634, 15, 19, 257 |
Multiply the prime numbers at the bottom and the left side.
31 x 634 x 15 x 19 x 257 = 1439557230
Therefore, the lowest common multiple of 634,465,589,257 is 1439557230.
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.
634 x 465 x 589 x 257 = 44626274130
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.
634 : 1, 2, 317, 634
465 : 1, 3, 5, 15, 31, 93, 155, 465
589 : 1, 19, 31, 589
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,465,589,257, is 1.
Now, the common factors can be found like this.
634:2x 317
465:3x 5x 31
589:19x 31
257:257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
31 = 31
Therefore, the value for common factors is 31.
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 = 44626274130/(1x31)
LCM = 44626274130/31
LCM = 1439557230
Thus, we can understand that the LCM of 634,465,589,257 is 1439557230.
