Given numbers are 408, 520, 402, 526

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(408, 520) = 26520

GCD(408, 520) = ( 408 x 520 ) / 26520

= 408 / 520

= 408

Step2:

LCM(8, 402) = 1608

GCD(8, 402) = ( 8 x 402 ) / 1608

= 8 / 402

= 8

Step3:

LCM(2, 526) = 526

GCD(2, 526) = ( 2 x 526 ) / 526

= 2 / 526

= 2

So, Greatest Common Divisor of 408, 520, 402, 526 is 2
