Question

5. The product of two numbers is 414720 and their HCF is 144. Find their LCM.
6. Write the prime factorisation of 6300.
​

Answer 1

Answer:

We know that

HCF×LCM= product of two numbers

144×LCM=414720

LCM=414720/144

\underline{\green {\bold {LCM}}}

LCM

=2,880

Or

the prime factors of the number 6,300. If we put all of it together we have the factors 2 x 2 x 3 x 3 x 5 x 5 x 7 = 6,300.
