Given numbers are 639,573,291,723,241
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,573,291,723,241 is 2853139473.
Find LCM of 639,573,291,723,241 with Prime Factorization
| 3 | 639, 573, 291, 723, 241 |
| 241 | 213, 191, 97, 241, 241 |
| 213, 191, 97, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 241 x 213 x 191 x 97 x 1 x 1 = 2853139473
Therefore, the lowest common multiple of 639,573,291,723,241 is 2853139473.
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.
639 x 573 x 291 x 723 x 241 = 18565378550811
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.
639 : 1, 3, 9, 71, 213, 639
573 : 1, 3, 191, 573
291 : 1, 3, 97, 291
723 : 1, 3, 241, 723
241 : 1, 241
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,573,291,723,241, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
573:3x 191
291:3x 97
723:3x 241
241:241
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 241 = 6507
Therefore, the value for common factors is 6507.
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 = 18565378550811/(1x6507)
LCM = 18565378550811/6507
LCM = 2853139473
Thus, we can understand that the LCM of 639,573,291,723,241 is 2853139473.
