Given numbers are 19,77,77,55,531
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 19,77,77,55,531 is 3884265.
Find LCM of 19,77,77,55,531 with Prime Factorization
7 | 19, 77, 77, 55, 531 |
11 | 19, 11, 11, 55, 531 |
19, 1, 1, 5, 531 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 19 x 1 x 1 x 5 x 531 = 3884265
Therefore, the lowest common multiple of 19,77,77,55,531 is 3884265.
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.
19 x 77 x 77 x 55 x 531 = 3289972455
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.
19 : 1, 19
77 : 1, 7, 11, 77
77 : 1, 7, 11, 77
55 : 1, 5, 11, 55
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 19,77,77,55,531, is 1.
Now, the common factors can be found like this.
19:19
77:7x 11
77:7x 11
55:5x 11
531:3x 3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 11 = 847
Therefore, the value for common factors is 847.
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 = 3289972455/(1x847)
LCM = 3289972455/847
LCM = 3884265
Thus, we can understand that the LCM of 19,77,77,55,531 is 3884265.
