Question

the LCM of 25 and 65 is 325 find their HCF​

Answer 1

Answer:

Given numbers are 25 and 65

Prime factorization of 25 = 5 x 5

Prime factorization of 65 = 5 x 13

HCF of 25 and 65 = 5

LCM of 25 and 65= 5 x 5 x 13 = 325

Product of the given numbers = 25 x 65 = 1, 625

Product of their HCF and LCM = 5 x 325 = 1, 625

Therefore, Product of the number = Product of their HCF and LCM

Answer 2

Answer:

5

Step-by-step explanation:

M.1:

Use the relation (H.C.F)*(L.C.M.) = Num1 * Num2

=> H.C.F.*325 = 65*25 = 1625

Therefore H.C.F. = 1625/325 = 5

M.2:

Factors of 25=(1,5,25)

Factors of 65=(1,5,13,65)

The largest common factor is 5, therefore 5 is the answer
