Given numbers are 876,546,702,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 876,546,702,782 is 280520604.
Find LCM of 876,546,702,782 with Prime Factorization
2 | 876, 546, 702, 782 |
3 | 438, 273, 351, 391 |
13 | 146, 91, 117, 391 |
146, 7, 9, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 146 x 7 x 9 x 391 = 280520604
Therefore, the lowest common multiple of 876,546,702,782 is 280520604.
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.
876 x 546 x 702 x 782 = 262567285344
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.
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
782 : 1, 2, 17, 23, 34, 46, 391, 782
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 876,546,702,782, is 2.
Now, the common factors can be found like this.
876:2x 2x 3x 73
546:2x 3x 7x 13
702:2x 3x 3x 3x 13
782:2x 17x 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 2x 3x 3x 13 = 468
Therefore, the value for common factors is 468.
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 = 262567285344/(2x468)
LCM = 262567285344/936
LCM = 280520604
Thus, we can understand that the LCM of 876,546,702,782 is 280520604.
