Answer 1

Answer:

5

Step-by-step explanation:

this is because every munber there is divisable by five. if you divide by 2 the muber 2205 wouldn't correspond when you are dividing

Answer 2

Answer:

LCM of the integers 2205 , 2520 , 8100 is 793800

Step-by-step explanation:

Given integers are 2205, 2520, 8100

Writing the prime factors for each integer

$2205=3\times3\times5\times7\times7$

$2520=2\times2\times2\times3\times3\times5\times7$

$8100=2\times2\times3\times3\times3\times3\times5\times5$

Now writing the highly repeated prime numbers from each integer, and multiplying

$2 \times 2 \times 2 \times 3 \times 3 \times 3 \times 3 \times 5 \times 5 \times 7 \times 7 = 793800$

Therefore, the LCM of the numbers is 793800
