(d) Factors of 27 = 3 x 3 x 3 \nFactors of 63 = 3 x 3 x 7 \nH.C.F. (27, 63) = 3 x 3=9<\/p>\n
(e) Factors of 36 = 2 x 2 x 3 x 3 \nFactors of 84 = 2 x 2 x 3 x 7 \nH.C.F. (36, 84) = 2x2x3 = 12<\/p>\n
(f) Factors of 34 = 2 x 17 \nFactors of 102 = 2 x 3 x 17 \nH.C.F. (34, 102) = 2 x 17 = 34<\/p>\n
(g) Factors of 70 = 2 x 5 x 7 \nFactors of 105 = 3 x 5 x 7 \nFactors of 175 = 5 x 5 x 7 \nH.C.F. = 5 x 7 = 35<\/p>\n
(h) Factors of 91 = 7 x 13 \nFactors of 112 = 2 x 2 x 2 x 2 x 7 \nFactors of 49 = 7 x 7 \nH.C.F. = 1 x 7 = 7<\/p>\n
<\/p>\n
(i) Factors of 18 = 2 x 3 x 3 \nFactors of 54 = 2 x 3 x 3 x 3 \nFactors of 81 = 3 x 3 x 3 x 3 \nH.C.F. = 3×3 = 9<\/p>\n
(j) Factors of 12 = 2 x 2 x 3 \nFactors of 45 = 3 x 3 x 5 \nFactors of 75 = 3 x 5 x 5 \nH.C.F. = 1 x 3 = 3<\/p>\n
Question 2. \nWhat is the H.C.F. of two consecutive: \n(a) numbers? \n(b) even numbers? \n(c) odd numbers? \nAnswer: \n(a) H.C.F. of two consecutive numbers is 1. \n(b) H.C.F. of two consecutive even numbers be is. \n(c) H.C.F. of two consecutive odd numbers be is.<\/p>\n
Question 3. \nH.C.F. of co-prime numbers 4 and 15 was found as follows by factorisation: \n4 = 2 x 2 and 15 = 3 x 5 since there is no common prime factor, so H.C.F. of 4 and 15 is 0. Is the answer correct? If not, what is the correct H.C.F.? \nAnswer: \nNo, The correct H.C.F. is 1.<\/p>\n","protected":false},"excerpt":{"rendered":"
