LCM (Least Common Factor) is the multiplication of highest powers of the all the numbers.
Let, the numbers be x and y.
A/q
x = 3 × 5 × 5 = 3¹ × 5²
y = 3 × 3 × 7 × 7 = 3² × 7²
Highest powers of 3 = 3²
Highest power of 5 = 5²
Highest power of 7 = 7²
LCM = 3² × 5² × 7² = 9 × 25 × 49 = 11025
Hence,
LCM(x, y) = 11025
