First you need to find the prime factors of 28 and 42. 28= 7x22 42= 7x3x2 Then you multiply 7x3x22, the product of which is 84, which is your answer.
The prime factor decomposition of 84 is: 2 x 2 x 3 x 7 If you want to see my working (in case I made a mistake): 84/2=42 (42 is not prime), 42/2=21 (21 is not prime), 21/3=7 (7 is prime, so stop here) factors: 2,2,3 and 7
126 is a composite number; it has factors other than 1 and itself.The 12 factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126.The factor pairs of 126 are 1 x 126, 2 x 63, 3 x 42, 6 x 21, 7 x 18, and 9 x 14.The proper factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, and 63 or,if the definition you are using excludes 1, they are 2, 3, 6, 7, 9, 14, 18, 21, 42, and 63.The prime factors of 126 are 2, 3, 3, and 7. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The distinct prime factors of 126 are 2, 3, and 7.The prime factorization of 126 is 2 x 3 x 3 x 7 or, in exponential form, 2 x 32 x 7.-ProMode- Thank you :)1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126The factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126.
The concept of prime factorisation is normally applied to positive integers only. This is because once you consider negative numbers, the results become ambiguous. One of the most important theorems of factorisation is that the prime factorisation of any integer is unique. That does not apply to negative integers. As long as an odd number of factors is negative, the overall product is negative so, -42 = -2*3*7 or 2*(-3)*7 or 2*3*(-7) : hardly unique!
We can get 29 by using their squares like: (42 + 32 + 22) / 1 = 29
42=2^3*7
Prime factors of 42 are 2 x 3 x 7. Using exponents, which is totally unnecessary when a number is to the first power, this would be 21 x 31 x 71.
2 x 3 x 7.
2 x 3 x 7 = 42 No exponents are needed.
the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3
It is: 126
42 and 48 2 x 3 x 7 = 42 24 x 3 = 48
The prime factorization of 42 does not use exponents: 2 x 3 x 7
It is: 32*25 = 288
378
No. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7
Least Common Multiple (LCM) for 8 42 is 168.
