Given numbers are 469,978,748,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 469,978,748,774 is 22129571772.
Find LCM of 469,978,748,774 with Prime Factorization
| 2 | 469, 978, 748, 774 |
| 3 | 469, 489, 374, 387 |
| 469, 163, 374, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 469 x 163 x 374 x 129 = 22129571772
Therefore, the lowest common multiple of 469,978,748,774 is 22129571772.
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.
469 x 978 x 748 x 774 = 265554861264
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.
469 : 1, 7, 67, 469
978 : 1, 2, 3, 6, 163, 326, 489, 978
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 469,978,748,774, is 1.
Now, the common factors can be found like this.
469:7x 67
978:2x 3x 163
748:2x 2x 11x 17
774:2x 3x 3x 43
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 = 265554861264/(1x12)
LCM = 265554861264/12
LCM = 22129571772
Thus, we can understand that the LCM of 469,978,748,774 is 22129571772.
