Solution : Factors of 5 = 1,5 <br> Factors of 12 = 1, 2, 3, 4, 6, 12 <br> 5 and 12 are co-primes, and we know that if a number is divisible by two co-primes, then it is a known fact that it is also divisible by their product. <br> The product of 5 and 12 is 60. Hence, the number is always divisible by 60. Therefore, if a number is divisible by both 5 and 12, it will be divisible by 60.
Question 3 Exercise 3.4
the given number will be divisible by the product of 5 and 12 i.e, it is always divisible by 5\times12=60.
So guys welcome to leader homework. Today. We are in question number six, which is a number is divisible by both 5 and 12 I have which another number or will that number be divisible? So this is a very easy thing to what you have to do is you have to just multiply the number by which numbers is that number divisible. So as it is divisible by 5 and 12 in this case, so you do five. Into 12/5, sorry. 5 x 12 which will If you answer at 60 and therefore the number, or which is always divisible by 5 and 12 both. It will always be divisible by 60 as well. Right? So even if it were other numbers like four and three here answer would come for you to breathe and stretch. So, this is a very easy thing. If you have any doubts, please let me know in the comments. Thank you so much. Have a great day guys.
