lowest common multiple of 168 n 180?

Question

may 1 noe wat is the LCM of 168 n 180???

Answer 1

168 = 2 * 2 * 2 * 3 * 7
180 = 2 * 2 * 3 * 3 * 5

so, LCM =
2 * 2 * 2 * 3 * 3 * 5 * 7 = 2520

Answer 2

Another method : GCD of 168 and 180 is 12 , you can find this using euclid algorithm
Notations :
a mod b => remainder when a is divided by b
b is less than a ,

a recursive function for GCD using above notations

GCD(a,b)
if b = 0 ; return a;
else return GCD(b,a mod b)

GCD(180,168) = GCD(168,12) = GCD(12,0) = 12
Now use LCM(a,b) * GCD(a,b) = a*b

so LCM(180,168) = (180 * 168)/12 = 168 * 15 = 2520

Answer 3

2520...this is the lowest number the is divisible by 168 and 180

Answer 4

2x2x3x14x15=2520
Just need to see which numbers divide into both and them multiply them together
