Given numbers are 257,634,160,843,370
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,634,160,843,370 is 406575932640.
Find LCM of 257,634,160,843,370 with Prime Factorization
2 | 257, 634, 160, 843, 370 |
5 | 257, 317, 80, 843, 185 |
257, 317, 16, 843, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 257 x 317 x 16 x 843 x 37 = 406575932640
Therefore, the lowest common multiple of 257,634,160,843,370 is 406575932640.
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.
257 x 634 x 160 x 843 x 370 = 8131518652800
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.
257 : 1, 257
634 : 1, 2, 317, 634
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
843 : 1, 3, 281, 843
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,634,160,843,370, is 1.
Now, the common factors can be found like this.
257:257
634:2x 317
160:2x 2x 2x 2x 2x 5
843:3x 281
370:2x 5x 37
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 = 8131518652800/(1x20)
LCM = 8131518652800/20
LCM = 406575932640
Thus, we can understand that the LCM of 257,634,160,843,370 is 406575932640.
