Answered by ansaf51

Answer:

HCF IS highest common factor

GCF IS greatest common factor

BOTH ARE SAME

1. 4

2. 6

3.7

Step-by-step explanation:

1.Greatest Common Factor of 24 and 28. Greatest common factor (GCF) of 24 and 28 is 4. We will now calculate the prime factors of 24 and 28, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 24 and 28.

2. We found the factors and prime factorization of 42 and 48. The biggest common factor number is the GCF number. So the greatest common factor 42 and 48 is 6.

3.Greatest Common Factor of 7 and 21. Greatest common factor (GCF) of 7 and 21 is 7. We will now calculate the prime factors of 7 and 21, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 7 and 21.
