Question

find the hcf and lcn of the numbers given below and verify their product is equal to the product of the given number.

1》18,63
2》25,45

please tell step by step​

Answer 1

Step-by-step explanation:

18*63=1134

now hcf = 63-18 =45

45 = 3*15= 3*3*5=9*5

here, 3 is common in 18&63

so, hcf =9

now, for lcm find largest one, ie, 63

63*2=126 is lcm

9*126=1134

similarly other question can be do.
