Given numbers are 698,915,874,635,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,915,874,635,309 is 3650891271990.
Find LCM of 698,915,874,635,309 with Prime Factorization
| 2 | 698, 915, 874, 635, 309 |
| 3 | 349, 915, 437, 635, 309 |
| 5 | 349, 305, 437, 635, 103 |
| 349, 61, 437, 127, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 349 x 61 x 437 x 127 x 103 = 3650891271990
Therefore, the lowest common multiple of 698,915,874,635,309 is 3650891271990.
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.
698 x 915 x 874 x 635 x 309 = 109526738159700
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.
698 : 1, 2, 349, 698
915 : 1, 3, 5, 15, 61, 183, 305, 915
874 : 1, 2, 19, 23, 38, 46, 437, 874
635 : 1, 5, 127, 635
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,915,874,635,309, is 1.
Now, the common factors can be found like this.
698:2x 349
915:3x 5x 61
874:2x 19x 23
635:5x 127
309:3x 103
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 5 = 30
Therefore, the value for common factors is 30.
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 = 109526738159700/(1x30)
LCM = 109526738159700/30
LCM = 3650891271990
Thus, we can understand that the LCM of 698,915,874,635,309 is 3650891271990.
