the numbers is
Answers
Answer:
q:2100
2 2 3 5 5 7
So there are 6 prime factors in 2100. in order to make two integers, each with an HCF of 5, we will need to split the set of factors such that there is a 5 in each set:
]a =. */ 2 2 3 5
60
]b =. */5 7
35
So the two integers would be 35 & 60
Check:
35 * 60
2100
HCF:
35 +. 60
5
LCM
35 *. 60
420
So the answer is 420 is the LCM of the two integers 35 & 60.

Answer:
3645
Step-by-step explanation:
let the numbers be x and y.
We know that,
x×y=Lcm×hcf.
therefore,x×280=135×7560
x=1,020,600/280
x=3645
