Given numbers are 651,939,690,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 651,939,690,899 is 1359099210.
Find LCM of 651,939,690,899 with Prime Factorization
| 3 | 651, 939, 690, 899 |
| 31 | 217, 313, 230, 899 |
| 7, 313, 230, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 31 x 7 x 313 x 230 x 29 = 1359099210
Therefore, the lowest common multiple of 651,939,690,899 is 1359099210.
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.
651 x 939 x 690 x 899 = 379188679590
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.
651 : 1, 3, 7, 21, 31, 93, 217, 651
939 : 1, 3, 313, 939
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,939,690,899, is 1.
Now, the common factors can be found like this.
651:3x 7x 31
939:3x 313
690:2x 3x 5x 23
899:29x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 31 = 279
Therefore, the value for common factors is 279.
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 = 379188679590/(1x279)
LCM = 379188679590/279
LCM = 1359099210
Thus, we can understand that the LCM of 651,939,690,899 is 1359099210.
