Given numbers are 168,182,718,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 168,182,718,407 is 319110792.
Find LCM of 168,182,718,407 with Prime Factorization
| 2 | 168, 182, 718, 407 |
| 7 | 84, 91, 359, 407 |
| 12, 13, 359, 407 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 12 x 13 x 359 x 407 = 319110792
Therefore, the lowest common multiple of 168,182,718,407 is 319110792.
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.
168 x 182 x 718 x 407 = 8935102176
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
182 : 1, 2, 7, 13, 14, 26, 91, 182
718 : 1, 2, 359, 718
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,182,718,407, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
182:2x 7x 13
718:2x 359
407:11x 37
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 7 = 28
Therefore, the value for common factors is 28.
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 = 8935102176/(1x28)
LCM = 8935102176/28
LCM = 319110792
Thus, we can understand that the LCM of 168,182,718,407 is 319110792.
