Question

use the relation between HCF and LCM of 15 , 20​

Answer 1

Answer:

LCM of 15 is 3×5 and LCM of 20 is 2×2×2and HcF of 15 and 20 is 15 and 8

Answer 2

Answer:

HCF*LCM=PRODUCT OF TWO NUMBERS

NOW BY THIS WE GET,

HCF*LCM=15*20

=300

=> LCM OF 300=2*2*3*5*5

AND WE KNOW HCF COMMON NUMBER OF BOTH NUMBERS LCM

=> LCM OF 15=3*5

LCM OF 20=2*2*5

=>HCF=5

AND,

LCM=15:-3*5

20:-2*2*5
