Yes, 4 and 21 are relatively prime. Numbers that are relatively prime only have the number 1 as a common factor. That is the case with 4 and 21.
The least common multiple of the numbers 7, 18 and 21 is 126.
Least Common Multiple (LCM) for 21 24 is 168.
Since 21 is a factor of 84, it is automatically the GCF. Since 84 is a multiple of 21, it is automatically the LCM.
Common factors of what? More info or this is not possible to answer.
As 4 & 21 have no factors in common, gcf=1
The Least Common Multiple (LCM) for 4 12 21 is 84.
LCM(4, 21) = 84
The LCM of 3 4 21 is 84.
LCM(4, 9, 21) = 252
The least common multiple of the numbers 4, 614 and 21 is 25,788.
The LCM of 4, 7, 12, and 21 is 84.
25
Just 1.
2/4 * * * * * No, it is 21/4 or 9/4
Yes, 4 and 21 are relatively prime. Numbers that are relatively prime only have the number 1 as a common factor. That is the case with 4 and 21.
Least Common Multiple (LCM) for 4 14 21 is 84.
