Question
The L.C.M. of 200 and 300 is____________
- 200
- 300
- 500
- 600
Hint:
The LCM of two numbers is the smallest number divisible by both numbers.
The correct answer is: 600
The L.C.M. of 200 and 300
200 = 2 · 2 · 2 · 5 · 5
300 = 2 · 2 · 3 · 5 · 5
So by taking all the common multiples once and non matching multiples as it is and multi[lying gives lcm by prime factorization method.
L.C.M = 2 · 2 · 2 · 3 · 5 · 5 = 600
Therefore, LCM of 200 and 300 is 600.
