The numbers 1, 2 and 4.
1,2.
The number that goes into both 12 and 72 equally is 12. This is because 72 divided by 12 equals 6, so 12 is a common divisor of both numbers.
1 and 3.
There is no number that goes into both. must be a trick questionthis is another person not the same one :)the number that goes into 12 and 21 is 3 which is a 5th grade problemwho ever said theres no number that goes into 12 and 21 is WRONG!
120 40x3=120, 12x10=120
The HCF of both numbers is 1
The HCF of both numbers is 6
The HCF of both numbers is 12
You probably mean it goes into both 'evenly'. That's 12
1 does and so does 2. There are others but ...
The GCF of both numbers is 6
1 and 3 will divide into both numbers with no remainders
