在小学数学里,两个正整数相乘,那么这两个数都叫做积的因数,或称为约数。

小学数学定义:假如a*b=c(a、b、c都是整数),那么我们称a和b就是c的因数。需要注意的是,唯有被除数,除数,商皆为整数,余数为零时,此关系才成立。 反过来说,我们称c为a、b的倍数。在研究因数和倍数时,小学数学不考虑0。

因数或称为约数:整数a除以整数b(b≠0) 的商正好是整数而没有余数,我们就说b是a的因数。0不是0的因数。

扩展资料

公约数与公倍数相反,就是既是A的约数同时也是B的约数的数,12和15的公约数有1,3,最大公约数就是3。再举个例子,30和40,它们的公约数有1,2,5,10,最大公约数是10。

公约数,亦称“公因数”。它是一个能被若干个整数同时均整除的整数。如果一个整数同时是几个整数的约数,称这个整数为它们的“公约数”;公约数中最大的称为最大公约数。对任意的若干个正整数,1总是它们的公因数。

如果数a能被数b整除,a就叫做b的倍数,b就叫做a的约数。约数和倍数都表示一个整数与另一个整数的关系,不能单独存在。如只能说16是某数的倍数,2是某数的约数,而不能孤立地说16是倍数,2是约数。
