7 is the correct answer
7
7 is the hcf
because its the highest number that divides into them all evenly. 91/7 is 13, 112/7 is 16, 49/7 is 7 So 13, 16 and 7 do not have anything else in common
It is: 7
49 = 7 x 7, 21 = 7 x 3, 91 = 7 x 13. HCF is 7
Because 7 is the largest positive integer that divides evenly into all of those numbers with no remainder.
The GCF is 7.
The GCF is 7.
The GCF is 7.
The GCF is 7.
The GCF is 7.
The GCF is 7.
HCF is the highest common factor of two or more numbers. HCF of 56 and 49 is 7.
HCF = 14
