Question

Find the HCF of the following pairs of numbers and hence use it to

find the LCM .

105, 245​

Answer 1

using euclid's division algorithm

245=105×2+35

105=35×3+0

HCF=35

We know,

HCF×LCM=Product of no.

35×LCM=105×245

LCM=105×245/35

LCM=245×3

LCM=735

Answer 2

Answer:

using euclid's division algorithm

245=105×2+35

105=35×3+0

HCF=35

We know,

HCF×LCM=Product of no.

35×LCM=105×245

LCM=105×245/35

LCM=245×3

LCM=735
