[German] [English]
 

Bcd (biggest common divisor): The biggest common divisor of two numbers is the biggest number through which it can be divided.

Example:

bcd (24, 36) = 12
bcd (4, 6, 8) = 2
bcd (13, 46) = 1 

Scm (smallest common multiple): The smallest common multiple is the smallest multiple of at least two numbers that the number is divisible by.

 

Examples:

scm (4, 6, 8) = 24
scm (5, 6) = 30
scm (2, 8) = 8
scm (4, 8) = 8
scm (3, 6, 9, 18) = 18
