Given numbers are 428, 730, 963, 247

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

Apply this formula for all numbers.

Step1:

LCM(428, 730) = 156220

GCD(428, 730) = ( 428 x 730 ) / 156220

= 428 / 730

= 428

Step2:

LCM(2, 963) = 1926

GCD(2, 963) = ( 2 x 963 ) / 1926

= 2 / 963

= 2

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 428, 730, 963, 247 is 1
