Answer 2

SOLUTION

TO DETERMINE

The product of smallest common multiple and the biggest common factor of 30,36 and 42

EVALUATION

Here the given three numbers are 30,36 and 42

$30 = 2 \times 3 \times 5$

$36 = 2 \times 2 \times 3 \times 3$

$42 = 2 \times 3 \times 7$

Now

Smallest common multiple

= 2 × 2 × 3 × 3 × 5 × 7

= 1260

Biggest common factor

= 2 × 3

= 6

Hence the required product

= 1260 × 6

= 7560
