The given numbers are co-prime and so the only common number is 1.
The numbers that go into both 85 and 68 evenly are their common divisors. The divisors of 85 are 1, 5, 17, and 85, while the divisors of 68 are 1, 2, 4, 17, 34, and 68. The greatest common divisor (GCD) of 85 and 68 is 17, so the numbers that divide both evenly are 1 and 17.
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.
If three of the four numbers are 79, 80, and 65, and the average is 85, then the final number will equal (85 x 4) - 79 - 80 - 65 = 116.
The numbers are in an arithmetic sequence (common difference = 6). Since there are 5 of them, their mean is the middle number: 79.
The Least Common Multiple of 17 and 85 is 85.
The greatest common factor of 17, 68, and 85 would have to be 17. This is due to the fact that 17 cannot be divided by anything except itself and zero. 68 can be divided by 17 four times, and 85 can be divided by 17 five times. This concludes that 17 would be the Greatest Common Factor of these three numbers.
