If the least common multiple of two numbers equals the product of the two numbers, then the numbers are relatively prime, that is their highest common factor is 1. For example, the numbers 10 and 21: The lcm is 10 x 21 = 210 They are relatively prime since their hcf is 1.
To find the LCM, you multiply the numbers together and then divide by the HCF. In this case, we don't know the numbers, but we have the HCF (13) and we have the product of the numbers (1690). Thus all you do is divide 1690 by 13 to get: 1690/13 = 130 And thus the LCM of two numbers whose hcf is 13 and product is 1690 is 130.
If the product of three numbers is 140, then we can write 140 as aXbXc. Let a be 10 and let b be 2. Then 140 equals 10X2Xc, or 7 equals c. Thus, the remaining number is 7.
The LCM of two numbers is sometimes the product of the two numbers.
16 and 25 23 and 47 27 and 50
There's only one number that equals 130. That number is . . . . . 130 .
10 and 13 have a difference of 3 and a product of 130. 13 - 10 = 3 13 x 10 = 130

The factor pairs of 130 are: 1 x 130 2 x 65 5 x 26 10 x 13
The two numbers that have a product of -240 and a sum of 1 are 16 and -15. This is because 16 multiplied by -15 equals -240, and 16 added to -15 equals 1. These two numbers satisfy both conditions simultaneously.
If the least common multiple of two numbers equals the product of the two numbers, then the numbers are relatively prime, that is their highest common factor is 1. For example, the numbers 10 and 21: The lcm is 10 x 21 = 210 They are relatively prime since their hcf is 1.

The product of two number is the result of the two numbers multiplied together. 41 times 63 equals 2583
