Question

explain me the HCF of 85 and 150 with method​

Answer 1

Factors of 100 = 1, 2, 5, 10, 20, 50 and 100. 

Factors of 150 (one hundred fifty) =1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75 and 150. 

Therefore, common factor of 100 and 150 = 1, 2, 3, 5, 10 and 50. 

Highest common factor (H.C.F) of 900 and 270 = 50. 

Answer 2

HCF of 85 and 150 by Euclid division lemma

150 = 85×1+65

150 =65×1+20

150=20×3+5

150=5×4+0

HCF of 150 and 85=5
