Given numbers are 428, 985, 955, 486

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

Apply this formula for all numbers.

Step1:

LCM(428, 985) = 421580

GCD(428, 985) = ( 428 x 985 ) / 421580

= 428 / 985

= 428

Step2:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 428, 985, 955, 486 is 1
