Given numbers are 428, 782, 904, 751

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

Apply this formula for all numbers.

Step1:

LCM(428, 782) = 167348

GCD(428, 782) = ( 428 x 782 ) / 167348

= 428 / 782

= 428

Step2:

LCM(2, 904) = 904

GCD(2, 904) = ( 2 x 904 ) / 904

= 2 / 904

= 2

Step3:

LCM(2, 751) = 1502

GCD(2, 751) = ( 2 x 751 ) / 1502

= 2 / 751

= 2

So, Greatest Common Divisor of 428, 782, 904, 751 is 1
