What is the LCM of 42 and 126 using prime factorization?
Bad example. 42 is a factor of 126. Therefore 126 has to be the LCM. By the numbers... 2 x 3 x 7 = 42 2 x 3 x 3 x 7 = 126, the LCM
What is the factor of 42 and 19?
Factor or Prime factor
What is the prime factor of 42 usig the factor tree?
42 21,2 7,3,2
What is the LCM of 56 42 and140 using prime factorization?
The LCM is: 840
What is the greatest common factor and the least common multiple of 6 and 14?
The GCF is 2. The LCM is 42.
What is the LCM of 3 and 42 using prime factor method?
3 2 x 3 x 7 = 42 Since 42 is a multiple of 3, it is automatically the LCM of the pair.
What is the Lcm of 14 and 42?
LCM(14, 42) = 42
What is the least common multiple of 42 and 13?
The answer is 246 ------------ Since 13 is a prime number and is not a factor of 42, the LCM will be 42x13 (=246).
How do you find the LCM with a factor tree?
The factor tree finds the prime factorization. The prime factorization finds the LCM. Example: 30 and 42 Factor them. 30 15,2 5,3,2 42 21,2 7,3,2 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM
What is the largest prime factor of 42?
The largest prime factor of 42 is 7
Is 42 a prime factor?
No. 42 is composite and therefore cannot be a prime factor.
What is the LCM of 26 and 42?
To find the LCM of 26 and 42 you first need to break those numbers up into their prime factors. In this case, that would be: 26 = 2x13 42 = 2x3x7 The next step is to identify any common factors. In this case, both numbers have a 2 as a prime factor, so we can discard one of these. Take every other prime factor (2, 3, 7 and 13) and multiply them together to find the LCM: 2x3x7x13 = 546 Therefore the LCM of 26 and 42 is 546.
What is the LCM of 42 and 126 using prime factorization?
Bad example. 42 is a factor of 126. Therefore 126 has to be the LCM. By the numbers... 2 x 3 x 7 = 42 2 x 3 x 3 x 7 = 126, the LCM
What is the least common multiple of 6 and 42 is?
The LCM of 6 and 42 is 42. Since 42 is a multiple of 6, it is automatically the LCM.You can also find the prime factors of each number to get the LCM. Use each factor the most it was used in either number. Multiply the factors.6=2x342=2x3x72x3x7=42 is the LCMIt is 42 because 6*7 = 42 and 1*42 = 42
What is the Lcm of 42 and 140 by prime factorization?
Least Common Multiple (LCM) for 42 140 is 420.
What is the LCM of 42 126 using prime factorization?
the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3
