Answer 2

Answer:

HCF = 6  and LCM = 319104

Step-by-step explanation:

1152 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3

1662 = 2 × 3 × 277

To find the HCF, multiply all the prime factors common to both numbers:

Therefore, HCF = 2 × 3

HCF = 6

LCM:-

Prime factors of 1152 =  $2^{7}$ × $3^{2}$

Prime factors of 1662 = 2 × 3 × 7

• Choose the common and uncommon prime factors with the greatest exponent

Common prime factors: 2,3

Common prime factors with the greatest exponent:  $2^{7}$,  $3^{2}$

Uncommon prime factors: 277

Uncommon prime factors with the greatest exponent: $277^{1}$

LCM = $2^{7}$ × $3^{2}$ × $277^{1}$

LCM = 319104
