A number is divisible by both 5 and 12. By which other number will that number be always divisible?
Answer :
It can be shown.
Let the number be p.
p = 12 × q [Given: p is divisible by 12]
Also, p is divisible by 5, but 12 is not divisible by 5, and do not have any factor common
So, q is divisible by 5.
p = 12 × (5 × r)
p= (12 × 5)r
p= 60r
So the number is divisible by 60.
