Q: What is the gcm of 3 7 and 9?

Write your answer...

The gcm for 9 and 12 would be 3. :)

There can be no GCM (Greatest Common Multiple). Suppose a GCM exists and suppose it is x. That is, x is the GCM of 7 and 13, then 2x is a multiple of both 7 and 13 and is greater than x. This contradicts the statement that x is the GCM. So x cannot be the GCM.

GCM(3, 4) = 1. The numbers are coprime.

The greatest common multiple of any set of integers is infinite.

The GCM would be 9 because if you multiply 9*4=36 9*5=45 9*7=63(:

9*18=162

27353563765263

The greatest common multiple of any set of integers is infinite.

There is not a unique answer. (3,36) and (9,12) are two possible solutions.

Density = Mass/Volume = 112/24 gcm-3 = 4.667 gcm-3

0.791 gcm-3. :)

60

[3/(-7)]* (-9) = (3/7)*9 = 27/7 = 3.857 approx.

Density = mass/volume = 18/25 gcm-3 = 0.72 gcm-3

LCM is 315. GCM would be infinite so I assume you mean GCF which would be 7

improper fraction of 3 - 7 over 9 = 34/9 3 7/9:= [(9 * 3)+7]/9= [27+7]/9= 34/9 in improper fraction

Because any two of the three numbers are coprime. That is, they do not have any factor, other than 1, in common.

{ [(1+3) *5 ] +7 } /9 = 3 [4 *5] + 7 = 27 divided by 9 = 3 also [ (1+3) / (5+7) ] * 9 = 3 More complex is 13 * (5+7) - 9 = 3 with just signs : -1 -3 +5 -7 + 9 = 3

3 = 9/3 = 21/73 = 9/3 = 21/7

The answer is: -30

9 x 3/7 = 9/1 x 3/7 = 9x3/1x7 = 27/7 = 36/7

3n + 7 = 163n + 7 - 7 = 16 - 73n + 7 - 7 = 16 - 73n = 16 - 73n = 93n/3 = 9/33n/3 = 9/3n = 9/3n = 3Check:3 x 3 + 7 =? 169 + 7 =? 1616 =? 16n=3 is the correct answer.

6=2*3 7=7 8=2*2*2 6 and 8 both have 2's, but 8 has more. Cross out the 2 from 6. 3*7*2*2*2 =168

18 = 2 x 3 x 3 105 = 3 x 5 x 7 the only common factor is a 3, and also the gcm is 3

7/9 - 3/9 = 4/9
