Given numbers are 861,854,611,973,577
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,854,611,973,577 is 5147481634386.
Find LCM of 861,854,611,973,577 with Prime Factorization
| 7 | 861, 854, 611, 973, 577 |
| 123, 122, 611, 139, 577 |
Multiply the prime numbers at the bottom and the left side.
7 x 123 x 122 x 611 x 139 x 577 = 5147481634386
Therefore, the lowest common multiple of 861,854,611,973,577 is 5147481634386.
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.
861 x 854 x 611 x 973 x 577 = 252226600084914
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
854 : 1, 2, 7, 14, 61, 122, 427, 854
611 : 1, 13, 47, 611
973 : 1, 7, 139, 973
577 : 1, 577
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,854,611,973,577, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
854:2x 7x 61
611:13x 47
973:7x 139
577:577
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 252226600084914/(1x49)
LCM = 252226600084914/49
LCM = 5147481634386
Thus, we can understand that the LCM of 861,854,611,973,577 is 5147481634386.
