Given numbers are 861, 413, 228, 985

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

Apply this formula for all numbers.

Step1:

LCM(861, 413) = 50799

GCD(861, 413) = ( 861 x 413 ) / 50799

= 861 / 413

= 861

Step2:

LCM(7, 228) = 1596

GCD(7, 228) = ( 7 x 228 ) / 1596

= 7 / 228

= 7

Step3:

LCM(1, 985) = 985

GCD(1, 985) = ( 1 x 985 ) / 985

= 1 / 985

= 1

So, Greatest Common Divisor of 861, 413, 228, 985 is 1
