LCM (a,b) `xx` HCF(a,b)= _________

If a and b are any two positive integers then HCF (a,b) xx LCM (a,b) is equal to

For two positive integers a and b, HCF (a, b) x LCM (a, b) = a x b.

If HCF(a,b)=45 and a times b=30375 ,then LCM (a,b) is: (a) 1875, (b) 1350, (c) 625, (d) 675

Consider the following in respect of natural numbers a, b and c: 1. LCM (ab, ac) = a LCM(b, c) 2. HCF(ab, ac) = a HCF(b, c) 3. HCF (a, b) lt LCM (a, b) 4. HCF (a, b) divides LCM(a, b). Which of the above are correct?

For two positive integers a and b, if HCF (a, b) = 7 and LCM (a, b) = 385, then their product is ..........

("HCF of given fraction")/("LCM of given fractions") =(HCF " of numerators" xx HCF " of denominators")/("LCM of denominators" xx) ______.
