Translation guide
In mathematics, a divisor is a number that divides another number evenly. This guide covers how to express this concept in Japanese, including common terms and usage in arithmetic and algebra.
The number that divides another number in a division operation, especially in integer division without remainder.
The standard term for a divisor in the context of integer divisibility. It refers to a number that divides another number exactly, leaving no remainder.
The bottom part of a fraction, also known as the denominator.
The denominator of a fraction. While 'divisor' can sometimes refer to the denominator, in Japanese it's specifically 分母.
約数 is used when discussing factors and divisibility (e.g., 'divisors of 12'), while 除数 is used in the context of the division algorithm (dividend ÷ divisor = quotient). In many everyday math contexts, they overlap, but 約数 emphasizes the integer factor relationship.
12の約数をすべて求めなさい。
Find all divisors of 12.
除数が0の場合は計算できません。
You cannot calculate when the divisor is 0.
The divisors of 6 are 1, 2, 3, and 6.
Refers to the divisor in a division operation (dividend ÷ divisor = quotient). More formal and used in arithmetic contexts.
割り算では、割られる数を被除数、割る数を除数といいます。
In division, the number being divided is called the dividend, and the number dividing it is called the divisor.
A plain, everyday way to say 'the number that divides'. Used in elementary math or casual explanations.
この問題では、割る数が3です。
In this problem, the divisor is 3.
分数の分母は、全体をいくつに分けるかを示します。
