The LCM of both numbers is 84
7
1 and 7 will go into both the two given numbers
2 can go into 4 but nothing can go into 7
Both 5 and 7 are prime numbers, so the only number that could go into both evenly would be 1.
The HCF of both numbers is 7
1 and 7
1 and 7 will go into both numbers evenly with no remainders
The numbers are coprime, so the answer is 1.
1 and 7 will go into both numbers evenly with no remainders
These numbers go into 28 evenly: 1, 2, 4, 7, 14, 28.
The LCD of both numbers is 28
