Given numbers are 771,663,695,855,448
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,663,695,855,448 is 3024017680320.
Find LCM of 771,663,695,855,448 with Prime Factorization
3 | 771, 663, 695, 855, 448 |
5 | 257, 221, 695, 285, 448 |
257, 221, 139, 57, 448 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 257 x 221 x 139 x 57 x 448 = 3024017680320
Therefore, the lowest common multiple of 771,663,695,855,448 is 3024017680320.
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.
771 x 663 x 695 x 855 x 448 = 136080795614400
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.
771 : 1, 3, 257, 771
663 : 1, 3, 13, 17, 39, 51, 221, 663
695 : 1, 5, 139, 695
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,663,695,855,448, is 1.
Now, the common factors can be found like this.
771:3x 257
663:3x 13x 17
695:5x 139
855:3x 3x 5x 19
448:2x 2x 2x 2x 2x 2x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 136080795614400/(1x45)
LCM = 136080795614400/45
LCM = 3024017680320
Thus, we can understand that the LCM of 771,663,695,855,448 is 3024017680320.
