Given numbers are 496,800,674,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 496,800,674,690 is 576674400.
Find LCM of 496,800,674,690 with Prime Factorization
| 2 | 496, 800, 674, 690 |
| 2 | 248, 400, 337, 345 |
| 2 | 124, 200, 337, 345 |
| 2 | 62, 100, 337, 345 |
| 5 | 31, 50, 337, 345 |
| 31, 10, 337, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 31 x 10 x 337 x 69 = 576674400
Therefore, the lowest common multiple of 496,800,674,690 is 576674400.
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.
496 x 800 x 674 x 690 = 184535808000
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.
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
674 : 1, 2, 337, 674
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 496,800,674,690, is 2.
Now, the common factors can be found like this.
496:2x 2x 2x 2x 31
800:2x 2x 2x 2x 2x 5x 5
674:2x 337
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 2x 2x 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 184535808000/(2x160)
LCM = 184535808000/320
LCM = 576674400
Thus, we can understand that the LCM of 496,800,674,690 is 576674400.
