greater

When one factor is less than one, the product will be less than the other factor.

When they have a common prime factor. When their GCF is greater than 1.

It means to express a number as the product of its factors. Factors are either composite numbers or prime numbers (except that 0 and 1 are neither prime nor composite).

In your example, the easiest way to estimate the product would be to round each factor to the nearest 10, 100, 1,000 or whatever the factors are. So, for 6,893 * 556, round to 7,000 * 600 to get an estimate. Since both numbers are rounded up, you know your estimate will be high, but this is an easy way to get a close answer. To be specific here, 7,000 and 600 would be multiplied to get 4,200,000. You multiply the first digits together, and then add the total number of zeroes in each rounded number to your answer.

9X60

You cannot since the suggested method will always lead to an underestimate.

9 x 500 = 4500 and 9 x 600 = 5400, so you know the answer will be close to halfway between those two numbers. The actual answer is 4860.

Compatible numbers would be easier. Rounding gives you 14 x 47. Compatible numbers could be 13 x 50 which would be closer to the actual product.

The terms (factors) used in multiplication are the multiplicand (the factor being multiplied), the multiplier (the factor that the multiplicand is multiplied by) and the product (the answer, or results of the multiplication). Any time either of the factors is greater than the other by at least one, the product will always be greater than the largest factor.

In the equation 4 x 9 = 36, the product (36) is greater (larger) than each factor (4 and 9).

The product is less than the other factor. For example: 0.5 x 6 = 3. 3 is less than the factor that is greater than 1 (which is 6).

greater

The answer would be an overestimate.

Their product.

70 x 20 = 1400

When one factor is less than one, the product will be less than the other factor.
