1 yard equals 3 feet, 17x3=51, so 17yards equals51 feet.
5.66666666666
51 is the LCM. Since both numbers are primes, they can have no common factors.This tells us the LCM will always be their product which is 17x3=5151
17x1=17 17x2=34 17x3=51 17x4=68 17x5=85 17x6=102 17x7=119 17x8=136 17x9=153 17x10=170
Nine years later, John will be 17 and his father will be 51. 17x3=51
A multiple of any number is the number times the given number it is to be multiplied by. Example, the first multiple of 17 is 34, (17x2=34) The second multiple is 51, (17x3=51), the third is 68, (17x4=68) and so on. So, 17 times anything will equate to a multiple of 17 because it can be divided back the same number of times to become 17 again.
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.
