Hi Friend ✋✋
First you need do prime factorisation to these numbers
25 = 5 × 5 × 1 = 5²
36 = 3 × 3 × 2 × 2 × 1 = 3² × 2²
42 = 7 × 3 × 2 × 1
58 = 29 × 2 × 1
then select the common multiple all the numbers having .... but it's only one..
then multiply all the prime factors which are highest power.
LCM = 5² × 3² × 2² × 7¹ × 29¹ = 1,82,700
hope it helps
