Given numbers are 521,721,889,170,182
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,721,889,170,182 is 105431159470.
Find LCM of 521,721,889,170,182 with Prime Factorization
2 | 521, 721, 889, 170, 182 |
7 | 521, 721, 889, 85, 91 |
521, 103, 127, 85, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 521 x 103 x 127 x 85 x 13 = 105431159470
Therefore, the lowest common multiple of 521,721,889,170,182 is 105431159470.
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 721 x 889 x 170 x 182 = 10332253628060
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
721 : 1, 7, 103, 721
889 : 1, 7, 127, 889
170 : 1, 2, 5, 10, 17, 34, 85, 170
182 : 1, 2, 7, 13, 14, 26, 91, 182
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,721,889,170,182, is 1.
Now, the common factors can be found like this.
521:521
721:7x 103
889:7x 127
170:2x 5x 17
182:2x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7 = 98
Therefore, the value for common factors is 98.
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 = 10332253628060/(1x98)
LCM = 10332253628060/98
LCM = 105431159470
Thus, we can understand that the LCM of 521,721,889,170,182 is 105431159470.
