Only 1, 7 is pair of numbers that has 7 as its least common multiple.
Given that,
Pairs ( 1, 7 ), ( 3, 4 ), ( 7, 21), ( 14, 28).
A pair or pairs to be determined that have 7 as its least common multiple.
What is arithmetic?
In mathematics, it deals with numbers of operations according to the statements.
What is Lowest Common Multiple?
In arithmetic, LCM is defined as the lowest common multiple of two integers X and Y, usually represented as by LCM X, Y, and is the smallest favorable integer that is dividable by both X and Y.
Since the Least common multiple of pair of numbers has 7, this is only possible for 1 * 7, because the LCM of 1 and7 is 7. So from given option 1, 7 is the required pair.
Thus, only 1, 7 is pair of numbers that has 7 as its least common multiple.
