Two or more numbers are needed to answer this.
The least common factor of 140 and 210 is 1. I think you meant the greatest common factor which would be 70.
28=2.2.7 140=2.2.5.7 LCM=2.2.5.7=140
The least common factor of any set of integers is 1.
Least common factor is always 1. If you meant least common multiple, it would be 140. If you meant greatestcommon factor, it would be 4.
You need at least two numbers to find a GCF.
You need at least two numbers to find a GCF.
The greatest common factor for these two numbers is 140.
The greatest common factor of 140 and 348 is 4.
The greatest common factor of 140 and 150 is 10.
The greatest common factor of 140 and 25 is 5.
The greatest common factor of 75 , 140 = 5
4 is the greatest common factor of 36 and 140.
