how many numbers between 251 and 750 are divisible by 3 or 15 but not by 9 or 25?
we have this rule for two numbers:
HCF*LCM=Product
;which need not be true for more than two numbers
i am trying to form a pattern for a specific case of more than two numbers
1. HCF(1,2)=1; LCM(1,2)=2; product=2
HCF*LCM=product/1
2. HCF(1,2,3)=1; LCM(1,2,3)=6; product=6
HCF*LCM=product/1
3. HCF(1,2,3,4)=1; LCM(1,2,3,4)=12; product=24
HCF*LCM=product/2
4. HCF(1,2,3,4,5)=1; LCM(1,2,3,4,5)=60; product=120
HCF*LCM=product/2
5. HCF(1,2,3,4,5,6)=1; LCM(1,2,3,4,5,6)=60; product=720
HCF*LCM=product/12
6. HCF(1,2,3,4,5,6,7)=1; LCM(1,2,3,4,5,6,7)=420; product=5040
HCF*LCM=product/12
7. HCF(1,2,3,...,8)=1; LCM(1,2,3,...,8)=840; product=40320
HCF*LCM=product/48
8. HCF(1,2,3,...,9)=1; LCM(1,2,3,...,9)=2520; product=362880
HCF*LCM=product/48
9. HCF(1,2,3,...,10)=1; LCM(1,2,3,...,10)=2520; product=3628800
HCF*LCM=product/144
10. HCF(1,2,3,...,11)=1; LCM(1,2,3,...,11)=277200; product=39916800
HCF*LCM=product/144
11. HCF(1,2,3,...,12)=1; LCM(1,2,3,...,12)=332640; product=479001600
HCF*LCM=product/1440
12. HCF(1,2,3,...,13)=1; LCM(1,2,3,...,13)=4324320; product=6227020800
HCF*LCM=product/1440
and so on.
i am unable to identify the pattern here. the product is being divided by 1,1,2,2,12,12,48,48,144,144,1440,1440,... So, in general, what should be the value of "k" for which HCF*LCM=product/k; for 1,2,3,...,n?

X^2+Y^2=75^2 Find the total No of Integral Solutions.
The natural number X becomes divisible by 10 when 6 is added to it. Also, if the unit's digit of X is made the leftmost digit, the ten's digit is made the unit's digit, the hundred's digit is made the ten's digit and so on, the resulting number is equal to 4X. It is given that X is the smallest number with these properties. What is the sum of the digits of X?
