Question

find the LCM and HCF of 840 and 144 by applying the fundamental theorem of arithmetic​

Answer 1

Answer:

We know that :

a= bq + r

840 = 144 × 5 + 90

144 = 90 × 1 + 54

90 = 54 × 1 + 36

54 = 36 × 1 + 18

36 = 18 × 2 + 0

$\sf{\therefore 18\:is\:the\:HCF}$

By fundamental theorem of arithmetic

➡840 = 144 × 5 + 90

➡144 = 90 × 1 + 54

➡90 = 54 × 1 + 36

➡54 = 36 × 1 + 18

➡36 = 18 × 2 + 0

Hence , HCF Of 840 And 144 is 18
