Given numbers are 678,930,428,894,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,930,428,894,774 is 432266066460.
Find LCM of 678,930,428,894,774 with Prime Factorization
2 | 678, 930, 428, 894, 774 |
3 | 339, 465, 214, 447, 387 |
113, 155, 214, 149, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 113 x 155 x 214 x 149 x 129 = 432266066460
Therefore, the lowest common multiple of 678,930,428,894,774 is 432266066460.
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.
678 x 930 x 428 x 894 x 774 = 186738940710720
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
428 : 1, 2, 4, 107, 214, 428
894 : 1, 2, 3, 6, 149, 298, 447, 894
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,930,428,894,774, is 2.
Now, the common factors can be found like this.
678:2x 3x 113
930:2x 3x 5x 31
428:2x 2x 107
894:2x 3x 149
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 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 186738940710720/(2x216)
LCM = 186738940710720/432
LCM = 432266066460
Thus, we can understand that the LCM of 678,930,428,894,774 is 432266066460.
