prime factorization methods (i) 80 and 120​

Answer 1

Answer:

Step-by-step explanation:

Factors of 80 = 2× 2× 2× 2× 5 = 2⁴ × 5

Factors of 120 = 2× 2× 2× 3× 5 = 2³× 3 × 5

HCF = 2³ × 5 = 2× 2× 2× 5 = 40

Step-by-step explanation:

What is the H

CF of 80 and 120?

• Find the prime factorization of 80. 80 = 2 × 2 × 2 × 2 × 5.
• Find the prime factorization of 120. 120 = 2 × 2 × 2 × 3 × 5.
• To find the GCF, multiply all the prime factors common to both numbers: Therefore, GCF = 2 × 2 × 2 × 5.
• HCF = 40.
