Given numbers are 769,520,133,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 769,520,133,338 is 691392520.
Find LCM of 769,520,133,338 with Prime Factorization
2 | 769, 520, 133, 338 |
13 | 769, 260, 133, 169 |
769, 20, 133, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 769 x 20 x 133 x 13 = 691392520
Therefore, the lowest common multiple of 769,520,133,338 is 691392520.
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.
769 x 520 x 133 x 338 = 17976205520
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.
769 : 1, 769
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
133 : 1, 7, 19, 133
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,520,133,338, is 1.
Now, the common factors can be found like this.
769:769
520:2x 2x 2x 5x 13
133:7x 19
338:2x 13x 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 13 = 26
Therefore, the value for common factors is 26.
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 = 17976205520/(1x26)
LCM = 17976205520/26
LCM = 691392520
Thus, we can understand that the LCM of 769,520,133,338 is 691392520.
