Given numbers are 132, 438, 285, 857

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

Apply this formula for all numbers.

Step1:

LCM(132, 438) = 9636

GCD(132, 438) = ( 132 x 438 ) / 9636

= 132 / 438

= 132

Step2:

LCM(6, 285) = 570

GCD(6, 285) = ( 6 x 285 ) / 570

= 6 / 285

= 6

Step3:

LCM(3, 857) = 2571

GCD(3, 857) = ( 3 x 857 ) / 2571

= 3 / 857

= 3

So, Greatest Common Divisor of 132, 438, 285, 857 is 1
