On a further note, you will need maths throughout your life so it's best not to get Answers to do your homework, or you will fail your state exams years down the road
hcf(10, 21) = 1 ⇒ 10 & 21 relatively prime hcf(12, 54) = 6 ⇒ 12 & 54 not relatively prime hcf(15, 27) = 3 ⇒ 15 & 27 not relatively prime hcf(21, 38) = 1 ⇒ 21 & 38 relatively prime
The GCF is 12.
None. But 4 and 6 have a LCM (not LMC) of 12 and HCF of 2.
The GCF is 12.It is: 12
It is: 1
The GCF is 2.
The GCF is 2.
It is 1 but the HCF is 2
The HCF of 12 and 60 is 12
The GCF is 12.
hcf(10, 21) = 1 ⇒ 10 & 21 relatively prime hcf(12, 54) = 6 ⇒ 12 & 54 not relatively prime hcf(15, 27) = 3 ⇒ 15 & 27 not relatively prime hcf(21, 38) = 1 ⇒ 21 & 38 relatively prime
The HCF of 40 & 12 is... 4
The GCF of 10 and 12 is 2, reducing 10/12 to 5/6
The hcf of 12 & 36 is 12
the HCF is 6
It is 1 which is their HCF
The GCF is 3.
