17 goes into itself once and it goes into 85 5 times. So write 17/85 as (17x1)/(17x5) and cancel the 17s. What is left is 1/5/
17x1=17 17x2=34 17x3=51 17x4=68 17x5=85 17x6=102 17x7=119 17x8=136 17x9=153 17x10=170
Original Price x .85 = 136 Original price = 136/.85 (If you are allowed to use a calculator, you are done here.) IF not, factor and cancel... 136X100/85 = 2x2x2x17x2x2x5x5/17x5 = 2x2x2x2x2x5 = 32 x 5 = 160 160
It is 6.
17x5= 85 Glad to help (:
The GCF is 17x5
17X5=85 85"
The Greatest common factor of 85 and 102 is 17. (17x5=85 and 17x6=102)17

GCF or "greatest common factor" is the largest number made of factors common to each of a set of numbers. If all three have only a single 5 as common factor, it is the GCF.15 and 20 (3x5 and 2x2x5) have a GCF of 5.65 and 75 (13x5 and 3x5x5).85 and 100 (17x5 and 2x2x5x5).The trivial answer is "5" and any other multiple of 5.5, 1010, 155, 15
The greatest number which divides both 51 and 85 is 17. So, greatest common factor is 17.Alternate method:P.F. of 51 = 3x17P.F. of 85 = 5x17Clearly, from the P.F. of both numbers 17 is the greatest common factor.The GCF is 17.51 and 85's highest common factor is 17.
