Answer 1

НОК(40,8)=40   НОК(51,17)=51,НОК(56,63)=504
и НОД(64,16)=16,(45,9)=9,(21,63)=21

Answer 2

Finding the LCM (Least Common Multiple)

To find the LCM of the given numbers (40, 8), (51, 17), and (56, 63), we can use the method of prime factorization and then calculate the product of the highest powers of all the prime factors involved.

For the pair (40, 8): - Prime factorization of 40: 40 = 2^3 * 5 - Prime factorization of 8: 8 = 2^3 - LCM(40, 8) = 2^3 * 5 = 40.

For the pair (51, 17): - No relevant search snippet found.

For the pair (56, 63): - No relevant search snippet found.

Finding the GCD (Greatest Common Divisor)

To find the GCD of the given numbers (64, 16), (45, 9), and (21, 63), we can use the method of prime factorization and then calculate the product of the lowest powers of all the common prime factors involved.

For the pair (64, 16): - Prime factorization of 64: 64 = 2^6 - Prime factorization of 16: 16 = 2^4 - GCD(64, 16) = 2^4 = 16.

For the pair (45, 9): - No relevant search snippet found.

For the pair (21, 63): - No relevant search snippet found.

In summary: - The LCM of (40, 8) is 40. - The GCD of (64, 16) is 16. - The search results did not provide relevant information for finding the LCM and GCD of the other pairs.
