The greatest common factor of 5p and 20pp is 5p.Factors of 20pp can be written out as 1p and 20p, 2p and 10p, 4p and 5p.Factors of 5p can be written as 1 and 5p or 1p and 5.The highest factor they both have in common is 5p.

Since 5p is a factor of 20p, it is automatically the GCF.

There is not a greatest common factor of a single number, such as 5p, because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.The factors of 5p are 1, 5, p, and 5p.Examples:The greatest common factor of 5p and 30p is 5p.The greatest common factor of 5p and 43p is p.The greatest common factor of 5p and 83 is 1, unless p is a multiple of 83, in which case the greatest common factor is 83.

The GCF is 5p.

30p = 20p + 5p + 5p 40p = 20p + 10p + 10p

1/4

9 x 5p 7 x 5p, 1 x 10p 5 x 5p, 1 x 20p 5 x 5p, 2 x 10p 3 x 5p, 1 x 10p, 1 x 20p 3 x 5p, 3 x 10p 1 x 5p, 4 x 10p 1 x 5p, 2 x 20p 1 x 5p, 2 x 10p, 1 x 20p

40 ways.

The GCF = 4. 20p - 60pq + 32q = 4(5p - 15pq + 8q).

20p,50p,5p,2p

5px4p=20p 5px5=25p so 20p-25p=-5p

Use 50p, 20p, 20p, 5p and two 2p coins.

20p + 10p + 5p + 1p = 36p

Different countries have different coinage. You have not specified a country. In the UK, for example, you could do 50p + 20p + 20p + 20p + 10p + 5p = 1.25p

13 ways. They are:10 x 5p8 x 5p + 1 x 10p6 x 5p + 2 x 10p6 x 5p + 1 x 20p4 x 5p + 3 x 10p4 x 5p + 1 x 10p + 1 x 20p2 x 5p + 4 x 10p2 x 5p + 2 x 10p + 1 x 20p2 x 5p + 2 x 20p5 x 10p3 x 10p + 1 x 20p1 x 10P + 2 x 20p1 x 50pNote that no modern British coins are made of silver, though. Coins of 5p and above are made of copper-nickel.

One 20p coin and one 5p coin.

a 20p and a 5p = 25p

1p , 50p , 2p , 10p , 20p .5p

50p+20p+10p+5p+2p+1p =88p

The simplest way is 2*10p

Two 20p coins and one 5p coin make 45p.

There are 67 ways.

A 20p and a 5p

20 + 8 = 28p

There are 47 ways using 5p, 10p, 20p and 50p.
