The H.C.F. of two numbers is 11 and their L.C.M. is 693. If one of the numbers is 77,find the other.
80
57
63
99
Let the required numbers be 15.x and 11x.
Then, their H.C.F. is x. So, x = 13.
The numbers are (15 x 13 and 11 x 13) i.e., 195 and 143.
ans is 99....because in case of two number : L.CM * H.C.F = First no. * second no.
so that 11 * 693= 77 * sec. no
second number = 99
Yes Ans is 99 only..
Another no. = (11*693)/77 = 99
YA..99
The Answer is 99 only.
Let x and y are two numbers. If the HCF,LCM and one number is given, the formula to find the second number is y=LCM * HCF / x.
Hence,
y= 693 * 11 / 77 = 99.
Please change the answer option
yes ans. is 99 bcz lcm*hcf=x*y
so 11*693=77*y
ans is 99
(HCF*LCM) of n1 and n2=multiplication of(n1*n2)
here one no. is given, lets take it n1=77, and HCF =11 and LCM=693
so. (11*693)=(77*n2)
hence n2=99
