Answer 2

$\huge{\begin{array}{c|c} 2 & 52 , 130 , 455 \\ \cline{1-2} 2 & 26 , 65 , 455 \\ \cline{1-2} 5 & 13 , 65 , 455 \\ \cline{1-2} 7 & 13 , 13 , 91 \\ \cline{1-2} 13 & 13 , 13 , 13 \\ \cline{1-2} & 1 , 1 , 1 \end{array}}$

$\tt{ LCM = 2 \times 2 \times 5 \times 7 \times 13 }$

= 4 ×5 ×7 × 13

= 20 ×7 ×13

= 140 × 13

= 1820

therefore , LCM of 52, 130 , 455 = 1,820

Additional Information :

→ LCM × HCF = Product of two numbers

Ex - Take two numbers 2 and 12

LCM = 12

HCF = 2

2 × 12 = 12 × 2

24 = 24

hence , verified .
