HCF of 15 20 and 25 is 150
then,
smallest 6 digit number = 100000
100000÷150=666 Remainder= 100
then, 100+50 = 150
so,
100000+50 = 100050 is the least six digit number exactly divisible be 15 20 and 25
then,
smallest 6 digit number = 100000
100000÷150=666 Remainder= 100
then, 100+50 = 150
so,
100000+50 = 100050 is the least six digit number exactly divisible be 15 20 and 25

============================
aim : to Find the least number of six digits which is exactly divisble by 15,20 and 25
=>least number of six digits = 10000
=>let us find the lcm of 15,20 and 25
=> 20 = 2x2x5
=> 25 = 5x5
=>15 = 3x5.
=> LCM = 2^2x5^2x3=300.
now let us divide 100000/300
=>333.333
=>now let us round of it to the next hundered
=>334
=>now,
=>334×300,
=>100200
hence 100200 is the
the least number of six digits which is exactly divisble by 15,20 and 25

hope it helps u..
