You cannot since the suggested method will always lead to an underestimate.
Factor
A product.
express 5610 as the product of prime factors
If you divide the product of two given numbers by their GCF, the result will be their LCM.
No. Factor pairs can be combined to create multiples.
9X60
2 x 6300 = 12,600 The actual answer is 12,508.
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 answer would be an overestimate.
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.
70 x 20 = 1400
If you are dividing the numerator and the denominator by the same number (the GCF), it is the same as dividing the fraction by 1, which will leave it unchanged and create the same product.
A factor multiplies with another factor to create a product.
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).
The identity property of multiplication states that any time a factor is multiplied by 1, the factor is unchanged.
