If you wish to find the Lowest Common Multiple (LCM) or Greatest Common Divisor (GCD) in Excel, this post will be helpful. We have covered both scenarios.

For example, the divisors of 12 are 1, 2, 3, 4, 6, and 12. The unitary divisors (those that have a greatest common divisor of 1) are 1, 3, 4, and 12. The first unitary amicable pair is 114 and 126.
