1, 2, 3, 6, 7, 14, 21, 42
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The factors of 39 are: 1, 3, 13, 39 The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The greatest common factor of 42 and 72 is 6 Gcf stands for Greatest Common Factor, The gcf of 42 and 72 is the largest positive number that is a factor of both 42 and 72. The positive factors of 42 (the integral divisors of 42) are: 1, 2, 3, 6, 7, 14, 21, and 42. The positive factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 36, and 72. Therefore the gcf of 42 and 72 is 6, as the greatest factor that 42 and 72 have in common.
I belive that it is 6
The common factors are: 1, 2, 3, 6.
42% of 72 = 42% * 72 = 0.42 * 72 = 30.24
To find the greatest common factor (GCF) of 42, 72, and 84, you first need to find the factors of each number. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The GCF of 42, 72, and 84 is the largest number that appears in the factors of all three numbers, which in this case is 6.
1, 2, 3 and 6
30 + 42 = 72
72 + 72 + 42 = 186
42 will not divide evenly into 72. You an divide 42 into 72 but there will be a fraction.
42 = 2 x 3 x 7 72 = 23 x 32 84 = 22 x 3 x 7
It is: 42+30 = 72
