1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1
The factors of 18 are 1, 2, 3 , 6, 9 & 18 because: 1 x 18 = 18 2 x 9 = 18 3 x 6 = 18
6 x 2 + 6 + 18
The LCM of 6, 18 and 32 is 288. 6 = 2 x 3 18 = 2 x 32 32 = 25 lcm = 25 x 32 = 288
1. 18 x 1 2. 9 x 2 3. 6 x 3
1, 2, 3, 6, 9, 18: (1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1)
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1
1 x 18 2 x 9 3 x 6 2 x 3 x 3
1, 2, 3, 6, 9, 18: 1 x 18, 2 x 9, 3 x 6
3(x + 2) = x - 18 3x + 6 = x - 18 3x - x = -18 - 6 2x = -24 x = -12
If you want to stick to integers: 1 x 18 = 18 2 x 9 = 18 3 x 6 = 18 -1 x -18 = 18 -2 x -9 = 18 -3 x -6 = 18
1, 2, 3 and 6
The GCF of 18 and 30 is 6.The factors of 18 are 1, 2, 3, 6, 9, and 18The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30So, the greatest common factor of the numbers 18 and 30 is 6.The GCF is 6.
1, 2, 3, 6, 9, 18, -1, -2, -3, -6, -9, -18
Prime factorization of 48 = 2 x 2 x 2 x 2 x 3Prime factorization of 18 = 2 x 3 x 3From the factorization of both numbers it is clear that 1, 2, 3 and 2x3 are common divisors. But 2x3 = 6 is the greatest among these, so GCD(48,18) = 6.
