Question

Find two numbers, both have an LCM of 882, smaller than 150 and a HCF of 21

Answer 1

Step-by-step explanation:

1. 882 many Lowest Common Multiples so we are going to eliminate all others more than 150 which leaves 14; 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126 and 147.

2. The next step is to remove all below 21 as it is not possible for the Highest Common Factor (HCF) to be larger than the two numbers.

3. 42 is definetely one of the numbers as it is double of 21.

4. The other number is 147 as it is less than 150 and shares an HCF of 21 with 42

Therefore, the answer is 42 and 147. Hope this helped mate and do tell if im wrong!
