Answer:
117 is the second number.
Step-by-step explanation:
Given : L.C.M. = 4680
H.C.F = 18
First no. = 720
To find: second number
Formula used: LCM ×HCF = 1st no. × 2nd no.
Solution:
LCM ×HCF = 1st no. × 2nd no.
4680 × 18= 720 × 2nd no.
Let 2nd number be X
Therefore X = 4680×18/720
X= 117

Answer:
117
Step-by-step explanation:
HCF(a,b)×LCM(a,b) = a×b
So,
18×4680=720×b
b=(18×4680)÷720
b=84240÷ 720
b=117
So the other number is 117.
