Given numbers are 77,20,99,929
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 77,20,99,929 is 12875940.
Find LCM of 77,20,99,929 with Prime Factorization
11 | 77, 20, 99, 929 |
7, 20, 9, 929 |
Multiply the prime numbers at the bottom and the left side.
11 x 7 x 20 x 9 x 929 = 12875940
Therefore, the lowest common multiple of 77,20,99,929 is 12875940.
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.
77 x 20 x 99 x 929 = 141635340
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.
77 : 1, 7, 11, 77
20 : 1, 2, 4, 5, 10, 20
99 : 1, 3, 9, 11, 33, 99
929 : 1, 929
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 77,20,99,929, is 1.
Now, the common factors can be found like this.
77:7x 11
20:2x 2x 5
99:3x 3x 11
929:929
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 141635340/(1x11)
LCM = 141635340/11
LCM = 12875940
Thus, we can understand that the LCM of 77,20,99,929 is 12875940.
