Answer 1

Answer:

1. HCF of 3 and 7 = 1

2.greater

3.Highest Common Factor

4.HCF of 35 and 49 = 7

6.whole

7.Prime numbers

Step-by-step explanation:

1. Prime factors of 3 and 7 are 3 and 7 only.

Factors of 3 and 7 are 1.

Hence , HCF/GCF(3,7) = 1 (here HCF and GCF refers to Highest Common Factor and Greatest Common Factor respectively).

4. Prime factorisation of

a) 35 = 5×7

b) 49 = 7×7

here, the common factor is 7 .

Hence, HCF(35,49) = 7
