Given numbers are 521,397,909,765,684
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,397,909,765,684 is 1214575821180.
Find LCM of 521,397,909,765,684 with Prime Factorization
3 | 521, 397, 909, 765, 684 |
3 | 521, 397, 303, 255, 228 |
521, 397, 101, 85, 76 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 521 x 397 x 101 x 85 x 76 = 1214575821180
Therefore, the lowest common multiple of 521,397,909,765,684 is 1214575821180.
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.
521 x 397 x 909 x 765 x 684 = 98380641515580
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.
521 : 1, 521
397 : 1, 397
909 : 1, 3, 9, 101, 303, 909
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,397,909,765,684, is 1.
Now, the common factors can be found like this.
521:521
397:397
909:3x 3x 101
765:3x 3x 5x 17
684:2x 2x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3 = 81
Therefore, the value for common factors is 81.
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 = 98380641515580/(1x81)
LCM = 98380641515580/81
LCM = 1214575821180
Thus, we can understand that the LCM of 521,397,909,765,684 is 1214575821180.
