Given numbers are 428, 172, 547

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

Apply this formula for all numbers.

Step1:

LCM(428, 172) = 18404

GCD(428, 172) = ( 428 x 172 ) / 18404

= 428 / 172

= 428

Step2:

LCM(4, 547) = 2188

GCD(4, 547) = ( 4 x 547 ) / 2188

= 4 / 547

= 4

So, Greatest Common Divisor of 428, 172, 547 is 1
