Given numbers are 478, 285, 59, 645

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

Apply this formula for all numbers.

Step1:

LCM(478, 285) = 136230

GCD(478, 285) = ( 478 x 285 ) / 136230

= 478 / 285

= 478

Step2:

LCM(1, 59) = 59

GCD(1, 59) = ( 1 x 59 ) / 59

= 1 / 59

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 478, 285, 59, 645 is 1
