Given numbers are 690,814,962,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,814,962,520 is 14603160.
Find LCM of 690,814,962,520 with Prime Factorization
| 2 | 690, 814, 962, 520 |
| 5 | 345, 407, 481, 260 |
| 13 | 69, 407, 481, 52 |
| 37 | 69, 407, 37, 4 |
| 69, 11, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 37 x 69 x 11 x 1 x 4 = 14603160
Therefore, the lowest common multiple of 690,814,962,520 is 14603160.
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.
690 x 814 x 962 x 520 = 280964798400
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
814 : 1, 2, 11, 22, 37, 74, 407, 814
962 : 1, 2, 13, 26, 37, 74, 481, 962
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,814,962,520, is 2.
Now, the common factors can be found like this.
690:2x 3x 5x 23
814:2x 11x 37
962:2x 13x 37
520:2x 2x 2x 5x 13
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 5x 13x 37 = 9620
Therefore, the value for common factors is 9620.
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 = 280964798400/(2x9620)
LCM = 280964798400/19240
LCM = 14603160
Thus, we can understand that the LCM of 690,814,962,520 is 14603160.
