Given numbers are 718,982,257,993,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 718,982,257,993,643 is 57849456238734.
Find LCM of 718,982,257,993,643 with Prime Factorization
2 | 718, 982, 257, 993, 643 |
359, 491, 257, 993, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 359 x 491 x 257 x 993 x 643 = 57849456238734
Therefore, the lowest common multiple of 718,982,257,993,643 is 57849456238734.
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.
718 x 982 x 257 x 993 x 643 = 115698912477468
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.
718 : 1, 2, 359, 718
982 : 1, 2, 491, 982
257 : 1, 257
993 : 1, 3, 331, 993
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,982,257,993,643, is 1.
Now, the common factors can be found like this.
718:2x 359
982:2x 491
257:257
993:3x 331
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 115698912477468/(1x2)
LCM = 115698912477468/2
LCM = 57849456238734
Thus, we can understand that the LCM of 718,982,257,993,643 is 57849456238734.
