Given numbers are 877,681,611,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 877,681,611,687 is 83564803803.
Find LCM of 877,681,611,687 with Prime Factorization
| 3 | 877, 681, 611, 687 |
| 877, 227, 611, 229 |
Multiply the prime numbers at the bottom and the left side.
3 x 877 x 227 x 611 x 229 = 83564803803
Therefore, the lowest common multiple of 877,681,611,687 is 83564803803.
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.
877 x 681 x 611 x 687 = 250694411409
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.
877 : 1, 877
681 : 1, 3, 227, 681
611 : 1, 13, 47, 611
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 877,681,611,687, is 1.
Now, the common factors can be found like this.
877:877
681:3x 227
611:13x 47
687:3x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 250694411409/(1x3)
LCM = 250694411409/3
LCM = 83564803803
Thus, we can understand that the LCM of 877,681,611,687 is 83564803803.
