Given numbers are 178,731,782,621,761
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 178,731,782,621,761 is 61491294558.
Find LCM of 178,731,782,621,761 with Prime Factorization
2 | 178, 731, 782, 621, 761 |
17 | 89, 731, 391, 621, 761 |
23 | 89, 43, 23, 621, 761 |
89, 43, 1, 27, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 89 x 43 x 1 x 27 x 761 = 61491294558
Therefore, the lowest common multiple of 178,731,782,621,761 is 61491294558.
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.
178 x 731 x 782 x 621 x 761 = 48086192344356
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.
178 : 1, 2, 89, 178
731 : 1, 17, 43, 731
782 : 1, 2, 17, 23, 34, 46, 391, 782
621 : 1, 3, 9, 23, 27, 69, 207, 621
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,731,782,621,761, is 1.
Now, the common factors can be found like this.
178:2x 89
731:17x 43
782:2x 17x 23
621:3x 3x 3x 23
761:761
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 23 = 782
Therefore, the value for common factors is 782.
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 = 48086192344356/(1x782)
LCM = 48086192344356/782
LCM = 61491294558
Thus, we can understand that the LCM of 178,731,782,621,761 is 61491294558.
