Answer 2

Answer:

The Highest common factor of the integers 42 , 63 , 90 is 3

Step-by-step explanation:

Given :

We are given there integers 42 , 63 , 90

To Find :

The Highest Common Factor of 42 , 63 , 90

Solution :

Since we are given three integers

To find the the Highest common factor we have to factorize the given integers

• The factors of 42 = 2 x 3 x 7
• The Factors of 63 = 3 x 3 x 7
• The Factors of 90 = 2 x 3 x 3 x 5

Hence the Highest common factor of the integers 42 , 63 , 90 is 3

Therefor the HCF is 3
