45 and 36 are not relatively prime because they have 3 as a common factor.
35, 36, 38, 39, 40, 42, 44, 45.
None of them is prime.
29 and 31 are prime. The rest are composite.
45 is NOT a prime number.
45 and 36 are not relatively prime because they have 3 as a common factor.
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, and 36.The prime factors of 36 are: 2 and 3.The factors of 45 are: 1, 3, 5, 9, 15, and 45.The prime factors of 45 are: 3 and 5.
To find the HCF of two numbers you first have to split them into their prime factors: 45 = 3x3x5 36 = 2x2x3x3 The next step is to identify any common prime factors. In this example, both numbers have two 3s as prime factors. Multiply these together and you get: 3x3 = 9 Thus the hcf of 45 and 36 is 9.
3 x 3 x 5 = 45 2 x 2 x 3 x 3 = 36
35, 36, 38, 39, 40, 42, 44, 45.
None of them is prime.
23, 29 and 31 are prime, the rest are composite.
29 and 31 are prime. The rest are composite.
Prime factor both numbers and use each the MOST it was used in any one number. 36=2x2x3x3 45=3x3x5 2x2x3x3x5=180
25 = 52 36 = 22 x 32 45 = 32 x 5 Since 25 and 36 have no prime factors in common other than 1, the GCF is 1.
100*45/36 = 125%
1, 3, 5, 9, 15, 45 3 and 5 are prime. 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72 2 and 3 are prime.
