Question

Calculate the Highest common factor of 130,260,390​

Answer 1

130

Explanation:

130 = 2x5x13

260 = 2x2x5x13

390 = 2x3x5x13

common factors = 2, 5, 13

therefore, 2x5x13 = 130

Cheers!

Answer 2

the Highest common factor of 130,260,390 = 130

130 = 2⋅5⋅13

260 = 2⋅2⋅5⋅13

390 = 2⋅3⋅5⋅13

Common multipliers (130; 260; 390): 2, 5, 13

Now to find the highest Common factor you need to multiply the common factors

Answer: (130 ; 260 ; 390) = 2 ∙ 5 ∙ 13 = 130
