Question

Plz help anybody will give branily

Answer 1

#8. The answer would be 189. The LCM (least common multiple) of 2 or more numbers, is the multiple that each number has in common with one another. Here are the multiples of both numbers up to 189, to show 189 is the answer.

• 21: 21, 42, 63, 84, 105, 126, 147, 168, 189
• 27: 27, 54, 81, 108, 135, 162, 189

#9. The answer would be 41. Prime numbers are numbers that only have 2 favtors (1 and itself). Since 41 is only divisible by 1 and itself, without the answer being a decimal, it is a prime number.

#10. The answer would be 6. The GCF (greatest common factor) of 2 or more numbers, is the largest factor that each number has in common with one another. Here are the factors of both numbers, to show 6 is the answer.

• 30: 1, 2, 3, 5, 6, 10, 15, 30.
• 48: 1, 2, 3, 4, 6, 8, 12, 24, 48.

I hope this helps!
