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.
2x2x2x3x5x7.
840
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.Since 840 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 840 is 840.You need at least two numbers to find a GCF.
The GCF of 320 and 840 is 40.
40
210
It is: 168
Since 280 is a factor of 840, it is automatically the GCF.
The GCF is 60.
The GCF is 40.
The GCF is 42.
The GCF is 120.
The GCF is 2.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 440 and 840 is 40.
