Given numbers are 547,851,498,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 547,851,498,690 is 1159087530.
Find LCM of 547,851,498,690 with Prime Factorization
| 2 | 547, 851, 498, 690 |
| 3 | 547, 851, 249, 345 |
| 23 | 547, 851, 83, 115 |
| 547, 37, 83, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 547 x 37 x 83 x 5 = 1159087530
Therefore, the lowest common multiple of 547,851,498,690 is 1159087530.
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.
547 x 851 x 498 x 690 = 159954079140
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.
547 : 1, 547
851 : 1, 23, 37, 851
498 : 1, 2, 3, 6, 83, 166, 249, 498
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 547,851,498,690, is 1.
Now, the common factors can be found like this.
547:547
851:23x 37
498:2x 3x 83
690:2x 3x 5x 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 3x 23 = 138
Therefore, the value for common factors is 138.
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 = 159954079140/(1x138)
LCM = 159954079140/138
LCM = 1159087530
Thus, we can understand that the LCM of 547,851,498,690 is 1159087530.
