Given numbers are 287, 189, 522, 784

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

Apply this formula for all numbers.

Step1:

LCM(287, 189) = 7749

GCD(287, 189) = ( 287 x 189 ) / 7749

= 287 / 189

= 287

Step2:

LCM(7, 522) = 3654

GCD(7, 522) = ( 7 x 522 ) / 3654

= 7 / 522

= 7

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 287, 189, 522, 784 is 1
