Given numbers are 721,876,486,219
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,876,486,219 is 51159276.
Find LCM of 721,876,486,219 with Prime Factorization
2 | 721, 876, 486, 219 |
3 | 721, 438, 243, 219 |
73 | 721, 146, 81, 73 |
721, 2, 81, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 73 x 721 x 2 x 81 x 1 = 51159276
Therefore, the lowest common multiple of 721,876,486,219 is 51159276.
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.
721 x 876 x 486 x 219 = 67223288664
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.
721 : 1, 7, 103, 721
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
219 : 1, 3, 73, 219
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,876,486,219, is 1.
Now, the common factors can be found like this.
721:7x 103
876:2x 2x 3x 73
486:2x 3x 3x 3x 3x 3
219:3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 73 = 1314
Therefore, the value for common factors is 1314.
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 = 67223288664/(1x1314)
LCM = 67223288664/1314
LCM = 51159276
Thus, we can understand that the LCM of 721,876,486,219 is 51159276.
