Question

aget Find the HCF by the start division method
a
100, 25, 50,10​

Answer 1

Step-by-step explanation:

Step I:

Divide the large number by the smaller one.

Step II:

Then the remainder is treated as divisor and the divisor as dividend.

Step III:

Divide the first divisor by the first remainder.

Step IV:

Divide the second divisor by the second remainder.

Step V:

Continue this process till the remainder becomes 0.

Step VI:

The divisor which does not leave a remainder is the H.C.F. or G.C.D. of the two numbers and thus, the last divisor is the required highest common factor (H.C.F) of the given numbers.

Let us consider some of the examples to find highest common factor (H.C.F) by using division method.

1. Find highest common factor (H.C.F) of 18 and 30 by using division method.

Answer 2

Answer:

Step-by-step explanation:

hcf of (100,25,50,10)

Factors of 100 are:

1 2 4 5 10 20 25 50 100

Factors of 25 are:

1 5 25

Factors of 50 are:

1 2 5 10 25 50

Factors of 10 are:

1 2 5 10

so hcf is 5
