Question
Do the given problems by repeated subtraction method and verify the result
320, 120 and 95
Solution
Let us take 320 and 120 first m = 320, n = 120
m – n = 320 – 120 = 200
m = 200, n = 120
∴ m – n = 200 – 120 = 80
120 – 80 = 40
80 – 40 = 40
∴ m = n = 40 → HCF of 320, 120
Now let us find HCF of 40 and 95
m = 95, n = 40
∴ m – n = 95 – 40 = 55
55 – 40 = 15
40 – 15 = 25
25 – 15 = 10
15 – 10 = 5
HCF of 40 and 95 is 5
10 – 5 = 5
∴ HCF of 320, 120 and 95 is 5
