Question

find the HCF of 332 and 255 , and check if these number are co-prime​

Answer 1

Answer:

the H.C.F of two numbers are 1 they are said to be co-prime

Factors of 14=1,2,7

Factors of 35=1,5,7

⇒ Common factor =1,7

∴ (14,35) is not pair of co-prime.

Factors of 18=1,2,3,6,9

Factors of 25=1,5

⇒ Common factor =1

∴ (18,25) is pair of co-prime.

Factors of 31=1,31

Factors of 93=1,3,31

⇒ Common factor =1,31

∴ (31,93) is not pair of co-prime.

Factors of 32=1,2,4,8,16

Factors of 62=1,2,31

⇒ Common factor =1,2

∴ (32,62) is not pair of co-prime.

Answer 2

Answer:

84660

Step-by-step explanation:

Method to find the least common multiple of 332 and 255 is by using the prime factorization method.

To use prime factorization, we first need to find the prime factors of 332 and 255, and then get the LCM by multiplying the prime factors that are rasied to their highest power from the two sets.

Prime factorization of 332 = 2 x 2 x 83 = 22 x 83

Prime factorization of 255 = 3 x 5 x 17

Prime factors to the highest power = 17 x 22 x 3 x 5 x 83 = 84660
