Given numbers are 257,429,602,561,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,429,602,561,643 is 725515676886.
Find LCM of 257,429,602,561,643 with Prime Factorization
3 | 257, 429, 602, 561, 643 |
11 | 257, 143, 602, 187, 643 |
257, 13, 602, 17, 643 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 257 x 13 x 602 x 17 x 643 = 725515676886
Therefore, the lowest common multiple of 257,429,602,561,643 is 725515676886.
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 429 x 602 x 561 x 643 = 23942017337238
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
429 : 1, 3, 11, 13, 33, 39, 143, 429
602 : 1, 2, 7, 14, 43, 86, 301, 602
561 : 1, 3, 11, 17, 33, 51, 187, 561
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,429,602,561,643, is 1.
Now, the common factors can be found like this.
257:257
429:3x 11x 13
602:2x 7x 43
561:3x 11x 17
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 23942017337238/(1x33)
LCM = 23942017337238/33
LCM = 725515676886
Thus, we can understand that the LCM of 257,429,602,561,643 is 725515676886.
