Answer:
HCF=1
Step-by-step explanation:
We want to find the HCF of
[tex]5 {x}^{5} [/tex]
[tex] {y}^{7} [/tex]
[tex]20 {x}^{3} [/tex]
HCF means the highest common factor.
We can find HCF by first expressing all the terms as product of prime factors and take the product of the least powers common to all three terms.
But we can observe directly that,
the only factor that is common to all three terms is 1.
Therefore the HCF is 1
