Answer:
Page number 840
Step-by-step explanation:
In order to find the page on which all three will be at, we must find out the LCM of 24 , 30 and 42.
By prime factorisation, we get,
24 = 2× 2 × 2 × 3
30 = 2 × 3 × 5
42 = 2 × 3 × 7
Hence,
LCM (24, 30 and 42) = 2 × 2 × 2 × 3 × 5 × 7
LCM (24, 30 and 42) = 840
Hence, 840 will be the page number where all three will be at on the same page.
