Given numbers are 428, 919, 647, 275

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

Apply this formula for all numbers.

Step1:

LCM(428, 919) = 393332

GCD(428, 919) = ( 428 x 919 ) / 393332

= 428 / 919

= 428

Step2:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

Step3:

LCM(1, 275) = 275

GCD(1, 275) = ( 1 x 275 ) / 275

= 1 / 275

= 1

So, Greatest Common Divisor of 428, 919, 647, 275 is 1
