Q: What is the LCM and the GCF of 18 and 21?

Write your answer...

The GCF is 3. The LCM is 252.

The GCF of 10 & 18 is 2.The LCM of 10 & 18 is 90.

LCM(12, 18, 24) = 72; GCF(12, 18, 24) = 6.

LCM 21, and GCF =1

GCF of 18 and 360 is 18 LCM of 18 and 360 is 360

The gcf and LCM of 21 and 26 are 1 and 546 respectively

The GCF is 6. The LCM is 360.

The LCM is 90. The GCF is 9.

The LCM of these numbers is 18. LCM is Least Common Multiple. The GCF of these numbers is 6. GCF is Greatest Common Factor.

The GCF is 9.

The LCM of 6 and 21 is 42. Their GCF is 3.

The LCM of 21 and 18 is 126.

The LCM is 360. The GCF is 6.

The LCM is 360. The GCF is 6.

The GCF is 3.

6 and 18v, respectively.

The LCM is 360.

Gcf: 7 lcm: 294

The GCF is 18.

LCM(21, 42, 18) = 126

6 and 72, respectively.

The GCF is 3. The LCM is 63.

Product of two numbers a and b = LCM(a,b) x GCF(a,b)...(1)Here, product of 18 and 360 = 6480Now, we shall find GCF of 18 and 360 by using the method of prime factorization.Prime factorization of 18 = 2x3x3Prime factorization of 360 = 2x2x2x3x3x5It is clear from the prime factorization that gcf = 18Now using (1) we can find LCM:LCM(18,360) = Product of 18 and 360/GCF(18,360) = 6480/18 = 360So, LCM and GCF of 18 & 360 is 360 and 18.Also, it is important to note that 360 is divisible by 18 then GCF is 18 and LCM is 360.

9 and 6 have an LCM of 18 and a GCF of 3.

21 and 63, respectively.
