The Greatest Common Factor of 30, 40: 10
Any multiple of 30 has these factors.
60.
The lowest common FACTOR of any set of numbers is 1. Perhaps you meant the Lowest Common MULTIPLE, which for 6, 10, 15 is 30. Or you meant the HIGHEST Common Factor, which for 6, 10, 15 is 1.
The greatest common factor of 60, 45, 30 would be 15. This is because all these numbers easily divide by 15. 60/15=4 45/15=3 30/15=2 Although these numbers are also all divisible by 5, 15 is greater than 5 making it the greatest common factor

the only factor (divisor) between 30 and 64 are 2, this is also a factor of 42 & 196 working upwards: 1 is always a factor of integers 2 is a factor of all even numbers 3 is a factor of 30 & 42, but not 64 or 196 4 is a factor of 64 & 196, but not 30 or 42 5 is a factor of 30, but not the others 6 is a factor of 30 & 42, but not 64 or 196 7 is a factor of 42, but not the others 8 is a factor of 64, but not the others 9 is not a factor of any of the numbers 10 is a factor of 30, but not the others I could continue, but it gets worse from there, with only occasional numbers being factors...
The two numbers that have the greatest common factor of ten are any two multiples of ten. This is because the greatest common factor is the largest number that divides evenly into both numbers. So, for example, 10 and 20 have a greatest common factor of 10 because 10 is the largest number that divides evenly into both 10 and 20.
