Given numbers are 578,778,731,103,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,778,731,103,860 is 9958252180.
Find LCM of 578,778,731,103,860 with Prime Factorization
2 | 578, 778, 731, 103, 860 |
17 | 289, 389, 731, 103, 430 |
43 | 17, 389, 43, 103, 430 |
17, 389, 1, 103, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 43 x 17 x 389 x 1 x 103 x 10 = 9958252180
Therefore, the lowest common multiple of 578,778,731,103,860 is 9958252180.
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.
578 x 778 x 731 x 103 x 860 = 29117929374320
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.
578 : 1, 2, 17, 34, 289, 578
778 : 1, 2, 389, 778
731 : 1, 17, 43, 731
103 : 1, 103
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,778,731,103,860, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
778:2x 389
731:17x 43
103:103
860:2x 2x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 17x 43 = 2924
Therefore, the value for common factors is 2924.
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 = 29117929374320/(1x2924)
LCM = 29117929374320/2924
LCM = 9958252180
Thus, we can understand that the LCM of 578,778,731,103,860 is 9958252180.
