Answer:

HCF = 12

Step-by-step explanation:

Expressing the numbers as products of their prime factors

84 = 2² × 3 × 7

120 = 2³ × 3 × 5

Identify the prime factors that both numbers have in common and multiply them.

Both have 2² and 3 in common, thus

HCF = 2² × 3 = 4 × 3 = 12

Write 240 and 1500 as products of their prime factor
Marina CMI [18]
240 = 2 × 120
120 = 2 × 60
60 = 2 × 30
30 = 2 × 15
15 = 3 × 5
The 2, 2, 2, 2, 3 and 5 are all the prime factors of 240. So, 2^4 × 3 × 5

1500 = 3 × 500
500 = 5 × 100
100 = 5 × 20
20= 5 × 4
4 = 2 × 2
The 3, 5, 5, 5, 2 and 2 are all the prime factors of 1500. So, 2² + 3 + 5³
