Given numbers are 540,565,257,177,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 540,565,257,177,138 is 21280663980.
Find LCM of 540,565,257,177,138 with Prime Factorization
| 2 | 540, 565, 257, 177, 138 |
| 3 | 270, 565, 257, 177, 69 |
| 5 | 90, 565, 257, 59, 23 |
| 18, 113, 257, 59, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 18 x 113 x 257 x 59 x 23 = 21280663980
Therefore, the lowest common multiple of 540,565,257,177,138 is 21280663980.
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.
540 x 565 x 257 x 177 x 138 = 1915259758200
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.
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
565 : 1, 5, 113, 565
257 : 1, 257
177 : 1, 3, 59, 177
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,565,257,177,138, is 1.
Now, the common factors can be found like this.
540:2x 2x 3x 3x 3x 5
565:5x 113
257:257
177:3x 59
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 1915259758200/(1x90)
LCM = 1915259758200/90
LCM = 21280663980
Thus, we can understand that the LCM of 540,565,257,177,138 is 21280663980.
