Given numbers are 647,306,565,626,521
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,306,565,626,521 is 18241318057590.
Find LCM of 647,306,565,626,521 with Prime Factorization
2 | 647, 306, 565, 626, 521 |
647, 153, 565, 313, 521 |
Multiply the prime numbers at the bottom and the left side.
2 x 647 x 153 x 565 x 313 x 521 = 18241318057590
Therefore, the lowest common multiple of 647,306,565,626,521 is 18241318057590.
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.
647 x 306 x 565 x 626 x 521 = 36482636115180
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.
647 : 1, 647
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
565 : 1, 5, 113, 565
626 : 1, 2, 313, 626
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,306,565,626,521, is 1.
Now, the common factors can be found like this.
647:647
306:2x 3x 3x 17
565:5x 113
626:2x 313
521:521
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 = 36482636115180/(1x2)
LCM = 36482636115180/2
LCM = 18241318057590
Thus, we can understand that the LCM of 647,306,565,626,521 is 18241318057590.
