1 find the hcf of the number by means of prime number a 52 and 78 b95 and 120

am suppose to use a square root please help me answer

a. Get the prime factorizations of 52 and 78:

52 = 2² • 13

78 = 2 • 3 • 13

Then the HCF/GCD of 52 and 78 is 2 • 13 = 26, because both 2 and 13 are common divisors of 52 and 78.

b. Do the same thing for 95 and 120:

95 = 5 • 19

120 = 2³ • 3 • 5

Then the HCF is 5.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
