Question

H.C.F / L.C.M ,21,24,36
​

Answer 1

Answer:

LCM = 504, HCF = 3

Step-by-step explanation:

HCF by long division method

21)24(1

21

"""""""'""

3)21( 7

21

"""""""""""'

00

now HCF of 3&36

3)36(12

3

""""""'

06

6

""""""""""

000

so, HCF of 21,24&36 is 3

now,

LCM of 21,24&36

2| 21, 24, 36

2| 21, 12, 18

3| 21, 6, 9

| 7, 2, 3

LCM = 2*2*3*7*2*3 = 504
