-
- another number is 52...
since, lcm*hcf = product of 2 numbers... - 11 years agoHelpfull: Yes(9) No(0)
- the other no is=(312*4)/24=52
- 11 years agoHelpfull: Yes(5) No(0)
- product of numbers=product of HCF & LCM
so, 24*x=312*4
x=52 - 8 years agoHelpfull: Yes(1) No(0)
- 24x=312*4
x=312*4/24
x=52 - 9 years agoHelpfull: Yes(0) No(0)
- product of numbers/ hcf of number = lcm of number
24x/4=312
6x=312
x=312/6
x=54 - 9 years agoHelpfull: Yes(0) No(1)
- lcm*hcf=product of two numbers
let x be the other no.
312*4=24*x
therefore , x=312*4/24=52 - 9 years agoHelpfull: Yes(0) No(0)
- Given: HCF=4 and LCM=312. Let the two numbers be n1 and n2. It is given that n1=24. We have to find the value of n2.
We know that HCF(n1,n2)* LCM(n1,n2)= n1*n2
i.e the product of HCF anf LCM for two numbers n1 and n2n is equals to the product of the numbers.
Thus;
n2=4*312/24
n2=52 - 8 years agoHelpfull: Yes(0) No(0)
