The prime factorization of 770 is 2 x 5 x 7 x 11. To find the prime factorization, you would start by dividing 770 by the smallest prime number, which is 2. This gives you 385. Then continue dividing by prime numbers until you reach only prime factors.
35. 350 = 2 x 52 x 7 385 = 5 x 7 x 11 hcf = 5 x 7 = 35
Starting with the number 4, applying the rule of multiplying by 2 and then subtracting 3 gives the following sequence: 4, 5, 7, 11, 19, 35. This pattern can be calculated as follows: 4 x 2 - 3 = 5, 5 x 2 - 3 = 7, 7 x 2 - 3 = 11, 11 x 2 - 3 = 19, 19 x 2 - 3 = 35.
