Given numbers are 865, 402, 430

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

Apply this formula for all numbers.

Step1:

LCM(865, 402) = 347730

GCD(865, 402) = ( 865 x 402 ) / 347730

= 865 / 402

= 865

Step2:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 865, 402, 430 is 1
