RRB Group-D Model Paper 19 with answers for online practice

Factors of 96 are 2, 2, 2, 2, 2, 3
Factors of 144 are 2, 2, 2, 2, 3, 3
Factors of 126 are 2, 3, 3, 7
Then multiply each factor the greatest number of times it occurs in each number. If the same factor occurs more than once in each number, you multiply the factor the greatest number of times it occurs.
∴ Least Common Multiple = 2 × 2 × 2 × 2 × 2 × 3 × 3 × 7 = 2016
