Answer:
2. answer =7
How to Find the GCF of 21 and 35 by Prime Factorization? To find the GCF of 21 and 35, we will find the prime factorization of the given numbers, i.e. 21 = 3 × 7; 35 = 5 × 7. ⇒ Since 7 is the only common prime factor of 21 and 35. Hence, GCF (21, 35) = 7.
3.answer =12
The GCF of 24 and 36 is 12. To calculate the GCF (Greatest Common Factor) of 24 and 36, we need to factor each number (factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24; factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36) and choose the greatest factor that exactly divides both 24 and 36, i.e., 12.
