Question

Please Help me...
Find the LCM and HCF of 72 and 108...
I will mark u as BRAINLIEST...

Answer 1

Answer:

LCM=36 and HCF=216

Step-by-step explanation:

72 = 2 x 2 x 2 x 3 x 3 - 1st set

108 = 2 x 2 x 3 x 3 x 3 -2nd set

for lcm we will only multiple those no. which are present in both set. so we get

LCM =2*2*3*3 =36

we have a Formula that is

the product of two no.= the product of LCM and HCF

72 x 108 = 36 x HCF

7776 = 36 HCF

HCF = 7776/36

HCF = 216

to check the answers you can use the formula

the product of two no. = HCF × LCM
