Question

Given that HCF (253,440) = 11 and LCM (253,440) = 253 × R. The value of R is:
(a) 400
(b) 440
(c) 40
(d) 253​

Answer 1

Step-by-step explanation:

Given:- HCF(253,440) = 11

LCM(253,440) = 253 × R

a = 253

b = 440

we know that,

HCF(a,b) × LCM(a,b) = a × b

HCF(a,b) × LCM(a,b) = a × b

11 × 253 × R = 253 × 440

2783 × R = 111320

R = 111320 ÷ 2783

R = 40
