Given numbers are 407,806,504,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 407,806,504,978 is 13474653192.
Find LCM of 407,806,504,978 with Prime Factorization
2 | 407, 806, 504, 978 |
3 | 407, 403, 252, 489 |
407, 403, 84, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 407 x 403 x 84 x 163 = 13474653192
Therefore, the lowest common multiple of 407,806,504,978 is 13474653192.
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.
407 x 806 x 504 x 978 = 161695838304
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.
407 : 1, 11, 37, 407
806 : 1, 2, 13, 26, 31, 62, 403, 806
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,806,504,978, is 1.
Now, the common factors can be found like this.
407:11x 37
806:2x 13x 31
504:2x 2x 2x 3x 3x 7
978:2x 3x 163
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 3 = 12
Therefore, the value for common factors is 12.
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 = 161695838304/(1x12)
LCM = 161695838304/12
LCM = 13474653192
Thus, we can understand that the LCM of 407,806,504,978 is 13474653192.
