Question

Find the HCF for the following:
28,36,45,60​

Answer 1

Answer:

HCF OF 28,36,45,60 = 1

Step-by-step explanation:

TO FIND THE HCF OF THE FOLLOWING,

WE HAVE TO TAKE THE COMMON FACTORS OF THE FOLLOWING,

SO,

FACTOR OF 28 = 2*2*7

FACTOR OF 36 = 2*2*3*3

FACTOR OF 45 = 3*3*5

FACTOR OF 60 = 2*2*3*5

AS,

THERE ARE NO COMMON FACTORS,

SO,

HCF OF 28,36,45,60 = 1

I HOPE YOU UNDERSTOOD THE QUESTION!!!

Answer 2

Answer:

=1

Explanation:

Prime Factorization of 28

=2x2x7x1

Prime Factorization of 36

=2x2x3x3x1

Prime Factorization of 45

=3x3x5x1

Prime Factorization of 60

=2x2x3x3x1

Find the common factors

28=2x2x7x1

36=2x2x3x3x1

45=3x3x5x1

60=2x2x3x3x1

And the common factor is =1

In the first I was confused about LCM and HCF
