First you round 312 to 310 and then you round 287.6 to 290, which equals, 20. ;)
The estimate for the product of 289 and 7 is 2,000.
These numbers are co-prime, ie have no common factor, so the LCM is the product, 312
7178 is a single number, there is no product involved.
Their product.
As a product of its prime factors: 2*2*2*3*13 = 312

Round 38 to 40. Estimate the product as 80. The actual product is 76.
YOU CAN estimate it by if your product has more than 5

when both factors in a multiplication problem are rounded up to estimate the product, the estimate is an overestimate.
Explain how you know whether an estimate of a product is an overestimate or an underestimate?
