Given numbers are 683,393,983,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 683,393,983,840 is 73879645560.
Find LCM of 683,393,983,840 with Prime Factorization
| 3 | 683, 393, 983, 840 |
| 683, 131, 983, 280 |
Multiply the prime numbers at the bottom and the left side.
3 x 683 x 131 x 983 x 280 = 73879645560
Therefore, the lowest common multiple of 683,393,983,840 is 73879645560.
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.
683 x 393 x 983 x 840 = 221638936680
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.
683 : 1, 683
393 : 1, 3, 131, 393
983 : 1, 983
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 683,393,983,840, is 1.
Now, the common factors can be found like this.
683:683
393:3x 131
983:983
840:2x 2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 221638936680/(1x3)
LCM = 221638936680/3
LCM = 73879645560
Thus, we can understand that the LCM of 683,393,983,840 is 73879645560.
