Question

LEVEL-1
1. Find the LCM and HCF of the following pairs of integers and verify that
(i) 26 and 91 (ii) 510 and 92
(iii) 336 and 54 (iv) 404 and 96 (CB
LCM X HCF = Product of the integers:​

Answer 1

Explanation:

i)numbers=26,91

26=1×2×13

91=1×7×13

so the hcf=13

lcm=182

product of integers=hcf ×lcm

=26×91=13×182

2366=2366

ii)510=1×2×3×5×17

92=1×2×2×23

hcf=2

lcm=23460

product of integers=lcm×hcf

510×92=2×23460

46920=46920

iii)336=1×2×2×2×2×3×7

54=1×2×3×3×3

hcf=6

lcm=3024

product of integers=hcf×lcm

336×54=3024×6

18144=18144

iv)404=1×2×2×101

96=1×2×2×2×2×2×3

hcf=4

lcm=9696

product of integers=hcf×lcm

404×96=9696×4

38784=38784

hope it helps
