Given numbers are 865,769,865,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,769,865,639 is 425053215.
Find LCM of 865,769,865,639 with Prime Factorization
5 | 865, 769, 865, 639 |
173 | 173, 769, 173, 639 |
1, 769, 1, 639 |
Multiply the prime numbers at the bottom and the left side.
5 x 173 x 1 x 769 x 1 x 639 = 425053215
Therefore, the lowest common multiple of 865,769,865,639 is 425053215.
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.
865 x 769 x 865 x 639 = 367671030975
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.
865 : 1, 5, 173, 865
769 : 1, 769
865 : 1, 5, 173, 865
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,769,865,639, is 1.
Now, the common factors can be found like this.
865:5x 173
769:769
865:5x 173
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 173 = 865
Therefore, the value for common factors is 865.
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 = 367671030975/(1x865)
LCM = 367671030975/865
LCM = 425053215
Thus, we can understand that the LCM of 865,769,865,639 is 425053215.
