Find the HCF of the following numbers using Common division method. ( a)75 , 125 (b) 72 , 108
Answers
Answer:
Step-by-step explanation:
Given
We need to find the Gcf of the numbers.
So we need to find the factors.
75 = 5 x 5 x 3
125 = 5 x 5 x 5
So the highest common factor is 5 x 5 = 25
72 = 2 x 2 x 2 x 3 x 3
108 = 2 x 2 x 3 x 3 x 3
Now the highest common factor is 2 x 2 x 3 x 3 = 36
Answer:
The H.C.F of the following numbers by using the common division method:
Case (a): 75, 125
75) 125 (
75
----------------------
50 ) 75 ( 1
50
-----------------------
H.C.F → 25 ) 50 ( 2
50
----------------------------
X ← remainder is zero
----------------------------
∴ The H.C.F of 75 & 125 = 25
Case (b): 72, 108
72) 108 (
72
----------------------
H.C.F → 36 ) 72 ( 2
72
-----------------------
X ← remainder is zero
----------------------------
