Given numbers are 665,771,895,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,771,895,423 is 12940413885.
Find LCM of 665,771,895,423 with Prime Factorization
3 | 665, 771, 895, 423 |
5 | 665, 257, 895, 141 |
133, 257, 179, 141 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 133 x 257 x 179 x 141 = 12940413885
Therefore, the lowest common multiple of 665,771,895,423 is 12940413885.
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.
665 x 771 x 895 x 423 = 194106208275
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
771 : 1, 3, 257, 771
895 : 1, 5, 179, 895
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,771,895,423, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
771:3x 257
895:5x 179
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 194106208275/(1x15)
LCM = 194106208275/15
LCM = 12940413885
Thus, we can understand that the LCM of 665,771,895,423 is 12940413885.
