Given numbers are 428, 164, 665, 783

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

Apply this formula for all numbers.

Step1:

LCM(428, 164) = 17548

GCD(428, 164) = ( 428 x 164 ) / 17548

= 428 / 164

= 428

Step2:

LCM(4, 665) = 2660

GCD(4, 665) = ( 4 x 665 ) / 2660

= 4 / 665

= 4

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 428, 164, 665, 783 is 1
