Given numbers are 428, 390, 453, 829

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

Apply this formula for all numbers.

Step1:

LCM(428, 390) = 83460

GCD(428, 390) = ( 428 x 390 ) / 83460

= 428 / 390

= 428

Step2:

LCM(2, 453) = 906

GCD(2, 453) = ( 2 x 453 ) / 906

= 2 / 453

= 2

Step3:

LCM(1, 829) = 829

GCD(1, 829) = ( 1 x 829 ) / 829

= 1 / 829

= 1

So, Greatest Common Divisor of 428, 390, 453, 829 is 1
