Given numbers are 730,351,778,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 730,351,778,731 is 72861306570.
Find LCM of 730,351,778,731 with Prime Factorization
2 | 730, 351, 778, 731 |
365, 351, 389, 731 |
Multiply the prime numbers at the bottom and the left side.
2 x 365 x 351 x 389 x 731 = 72861306570
Therefore, the lowest common multiple of 730,351,778,731 is 72861306570.
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.
730 x 351 x 778 x 731 = 145722613140
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.
730 : 1, 2, 5, 10, 73, 146, 365, 730
351 : 1, 3, 9, 13, 27, 39, 117, 351
778 : 1, 2, 389, 778
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,351,778,731, is 1.
Now, the common factors can be found like this.
730:2x 5x 73
351:3x 3x 3x 13
778:2x 389
731:17x 43
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 = 145722613140/(1x2)
LCM = 145722613140/2
LCM = 72861306570
Thus, we can understand that the LCM of 730,351,778,731 is 72861306570.
