Given numbers are 766,430,620,836,898
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,430,620,836,898 is 958189805980.
Find LCM of 766,430,620,836,898 with Prime Factorization
| 2 | 766, 430, 620, 836, 898 |
| 2 | 383, 215, 310, 418, 449 |
| 5 | 383, 215, 155, 209, 449 |
| 383, 43, 31, 209, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 383 x 43 x 31 x 209 x 449 = 958189805980
Therefore, the lowest common multiple of 766,430,620,836,898 is 958189805980.
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.
766 x 430 x 620 x 836 x 898 = 153310368956800
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.
766 : 1, 2, 383, 766
430 : 1, 2, 5, 10, 43, 86, 215, 430
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
898 : 1, 2, 449, 898
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,430,620,836,898, is 2.
Now, the common factors can be found like this.
766:2x 383
430:2x 5x 43
620:2x 2x 5x 31
836:2x 2x 11x 19
898:2x 449
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 5 = 80
Therefore, the value for common factors is 80.
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 = 153310368956800/(2x80)
LCM = 153310368956800/160
LCM = 958189805980
Thus, we can understand that the LCM of 766,430,620,836,898 is 958189805980.
