LCM of (a) and (b) is given as (ab)/(GCF(a,b)) To find the GCF, factor and find common factors. 50 factors to [2 5 5] 80 factors to [2 2 2 2 5] Common factors are [2 5] = 10 50 * 80 / 10 = 400 ■
Since 40 is a factor of 80, all of its factors are common.
To find the common factors of 25 and 80, we first determine the factors of each number. The factors of 25 are 1, 5, and 25, while the factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The common factors shared by both numbers are 1 and 5. To find the sum of these common factors, we add them together: 1 + 5 = 6. Therefore, the sum of all the common factors of 25 and 80 is 6.
The GCF is 10.
80
1, 2, 5 and 10
The factors of 50 are: 1, 2, 5, 10, 25, 50The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80The common factors are: 1, 2, 5, 10
Answer: 10Explination: These are the common factors--80-1,2,4,5,8,10,16,20,4050-1,2,5,10,25So the greatest common factor is 10.
Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80 Factors of 62: 1, 2, 31, 62 Factors of 50: 1, 2, 5, 10, 25, 50 GCF (80, 62, 50) = 2
LCM of (a) and (b) is given as (ab)/(GCF(a,b)) To find the GCF, factor and find common factors. 50 factors to [2 5 5] 80 factors to [2 2 2 2 5] Common factors are [2 5] = 10 50 * 80 / 10 = 400 ■
The common factors of 55 and 80 are 1 and 5
The greatest common factor of 80 and 50 is 10 :)
The factors of 50 are: 1, 2, 5, 10, 25, 50 The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
The common factors of 36 and 80 are: 1, 2, and 4
The common factors of 68 and 80 are 1, 2 and 4.
50 is not a prime number because it has more than 2 factors 10x5=50 1x50=50 and 80 is also not a prime because it has more than 2 factors 1x80=80 2x40= 80
The common factors are: 1, 5
