The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24. The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48 The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
We won't be able to find factors of 80 that are not factors of 80. The factors of 80 that aren't factors of 42 are 4, 5, 8, 10, 16, 20, 40 and 80.
THe GCF of 24 and 80 is 8. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24 The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80 The greatest common factor of 24 and 80 is 8
The factors of 16 are: 1, 2, 4, 8, 16 The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48 The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
factors of 12 are [2 2 3] factors of 80 are [2 2 2 2 5] common factors are [2 2] so the answer is 4.
The factors of 32 are: 1, 2, 4, 8, 16, 32 The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48 The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80 The factors of 81 are: 1, 3, 9, 27, 81 The factors of 82 are: 1, 2, 41, 82 The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48The factors of 64 are: 1, 2, 4, 8, 16, 32, 64The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72 The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80 ⇒ The common factors of 72 and 80 are: 1, 2, 4, 8,
80% of 12 = 80% * 12 = 0.8 * 12 = 9.6
12% of 80 = 12% * 80 = 0.12 * 80 = 9.6 or 960%
