Given numbers are 473, 129, 261, 402

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

Apply this formula for all numbers.

Step1:

LCM(473, 129) = 1419

GCD(473, 129) = ( 473 x 129 ) / 1419

= 473 / 129

= 473

Step2:

LCM(43, 261) = 11223

GCD(43, 261) = ( 43 x 261 ) / 11223

= 43 / 261

= 43

Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 473, 129, 261, 402 is 1
