Since 12 does not divide 54 and 6 does divide 54 the greatest common factor of 12 and 54 is 6.
What is the GCF of 12 and 36 using factor tree?
12
The GCF of 12 and 36 is 12. To calculate the greatest common factor (GCF) of 12 and 36, we need to factor each number (factors of 12 = 1, 2, 3, 4, 6, 12; factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36) and choose the greatest factor that exactly divides both 12 and 36, i.e., 12.
What is the prime factorization of 12 and 54?
Prime factorization of 54 and 12 is (2 × 3 × 3 × 3) = 21 × 33 and (2 × 2 × 3) = 22 × 31 respectively. LCM of 54 and 12 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 22 × 33 = 108. Hence, the LCM of 54 and 12 by prime factorization is 108.
What are the factors of the GCF is 12?
Factors of 12 are 1, 2, 3, 4, 6 and 12 … because 2 × 6 = 12, or 4 × 3 = 12, or 1 × 12 = 12.
What is the common factor of 54 and 42?
The GCF of 42 and 54 is 6. To calculate the greatest common factor of 42 and 54, we need to factor each number (factors of 42 = 1, 2, 3, 6, 7, 14, 21, 42; factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54) and choose the greatest factor that exactly divides both 42 and 54, i.e., 6.
What is the greatest common factor of 24 and 54?
