Given numbers are 698,462,990,320
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,462,990,320 is 77394240.
Find LCM of 698,462,990,320 with Prime Factorization
| 2 | 698, 462, 990, 320 |
| 3 | 349, 231, 495, 160 |
| 5 | 349, 77, 165, 160 |
| 11 | 349, 77, 33, 32 |
| 349, 7, 3, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 349 x 7 x 3 x 32 = 77394240
Therefore, the lowest common multiple of 698,462,990,320 is 77394240.
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 462 x 990 x 320 = 102160396800
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
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,462,990,320, is 2.
Now, the common factors can be found like this.
698:2x 349
462:2x 3x 7x 11
990:2x 3x 3x 5x 11
320:2x 2x 2x 2x 2x 2x 5
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 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 102160396800/(2x660)
LCM = 102160396800/1320
LCM = 77394240
Thus, we can understand that the LCM of 698,462,990,320 is 77394240.
