Given numbers are 985, 820, 663

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

Apply this formula for all numbers.

Step1:

LCM(985, 820) = 161540

GCD(985, 820) = ( 985 x 820 ) / 161540

= 985 / 820

= 985

Step2:

LCM(5, 663) = 3315

GCD(5, 663) = ( 5 x 663 ) / 3315

= 5 / 663

= 5

So, Greatest Common Divisor of 985, 820, 663 is 1
