let the first no. be x and the second no. be y
ReplyDeletex = 44 * 2 = 88
LCM = x * y/ HCF
264= 88 * Y/ 44
y = 264/2
y = 132
THEREFORE, OTHER NO. IS 132
132
ReplyDeleteAns. Let the two no.s be a & b, LCM = 264 , HCF = 44,
ReplyDeletea = 44 x 2
= 88
LCM = a x b / hcf
264 = 88 x b/44
b = 264/2
b = 132
therefore, the other no. is 132.
let 264 and 44 be lcm and hcf of a and b
ReplyDeletewhen 2 divides the first no. its quotient is 44 so 44 x 2 = a
a= 88
lcm = a x b/ hcf
lcm x hcf /a = b
264 x 44 / 88 = b
11616/88 = b
b = 132
LET NO BE A AND B
ReplyDeleteA= REMAINDER * QUOTIENT
=88
HCF * LCM = A * B
264 * 44=B88
(264*44)/88=B
B = 132
SO THE OTHER NO. IS 132
the answer is 132
