Given numbers are 986, 782, 439, 821

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

Apply this formula for all numbers.

Step1:

LCM(986, 782) = 22678

GCD(986, 782) = ( 986 x 782 ) / 22678

= 986 / 782

= 986

Step2:

LCM(34, 439) = 14926

GCD(34, 439) = ( 34 x 439 ) / 14926

= 34 / 439

= 34

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 986, 782, 439, 821 is 1
