Question

Find the HCF of the following using long division method
(a) 320, 420, 180​

Answer 1

Step-by-step explanation:

320 ÷180

Quotient = 1 ;Remainder = 140

180÷140

Quotient = 1; Remainder = 40

140÷40

Quotient = 3; Remainder =20

40÷20

Quotient = 2; Remainder =0

420÷20

Quotient =21; Remainder =0

Hence, the hcf of 320,420,180 is 20
