Question

Find the hcf and lcm of 6.72 and 120 using prime factorizationmethod

Answer 1

Hi there !

Fundamental theorem of arithmetic :

Fundamental theorem of arithmetic :Every composite number can be expressed as a product of primes, and this factorisation is unique except for theorder in which the prime factors occur.

H.C.F and L.C.M of 672 and 120

672= 2^5×3×7

120=2³×3×5

H.C.F (Lowest power) =3×2³

=24

L.C.M (Highest power) = 2^5×3×5×7

Thankyou :)
