Given numbers are 402, 154, 521

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

Apply this formula for all numbers.

Step1:

LCM(402, 154) = 30954

GCD(402, 154) = ( 402 x 154 ) / 30954

= 402 / 154

= 402

Step2:

LCM(2, 521) = 1042

GCD(2, 521) = ( 2 x 521 ) / 1042

= 2 / 521

= 2

So, Greatest Common Divisor of 402, 154, 521 is 1
