Question

find the LCM and HCF of being 17 23 29 with prime factorization method​

Answer 1

17,23,29 are prime numbers.they have only two factors i.e 1 and itself

factors of 17 =f(17)={1,17}

f(23)={1,23}

f(29)={1,29}

hcf of prime numbers =1

hcf(17,23,29)=1

lcm of prime numbers= product of the numbers

lcm(17,23,29)=17*23*29

2)8=2*2*2

9=3*3

25=5*5

hcf(8,9,25)=1(1 is common factor of each number)

lcm =8*9*25

i hope u can understand this:)  ,

sorry if u could not :(

Answer 2

17=17x1
23=23x1
29=29x1
so hcf =1
lcm=17x23x29
