What is the least common factor of 3 5 7 and 8?
The least common factor of any group of two or more numbers is always 1. The greatest common factor of 3, 5, 7, and 8 is also 1. The least common multiple (LCM) is the multiple of the highest power of prime factors in two or more numbers. Example: LCM of 3, 5, 7, and 8 is 840, which is the multiple of the highest power of all their prime factors, 23 x 3 x 5 x 7.
