Given numbers are 428, 543, 644, 575

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

Apply this formula for all numbers.

Step1:

LCM(428, 543) = 232404

GCD(428, 543) = ( 428 x 543 ) / 232404

= 428 / 543

= 428

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 575) = 575

GCD(1, 575) = ( 1 x 575 ) / 575

= 1 / 575

= 1

So, Greatest Common Divisor of 428, 543, 644, 575 is 1
