Answer:
72
Step-by-step explanation:
write 864 as a product of prime factor
864=2x2x2x2x2x3x3x3
write the prime factor as a product of 2 mutiples of 12
(2x2x2x3) x (2x2x3x3) =24x36
Mutiply the common pairs of prime factors from the rackets gives the hcf
HCF= 2x2x3=12 (2 is common twice and 3 is common once)
Multipy all the prime factors from the first brackets and any extras from the second bracket gives the lmc(there is an extra 3 in the second bracket)
Lcm=2x2x2x3x3=72
Hope this help mate, and follow me, or brainlist me, or thank me your choice.
