Given numbers are 423, 402, 56, 863

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

Apply this formula for all numbers.

Step1:

LCM(423, 402) = 56682

GCD(423, 402) = ( 423 x 402 ) / 56682

= 423 / 402

= 423

Step2:

LCM(3, 56) = 168

GCD(3, 56) = ( 3 x 56 ) / 168

= 3 / 56

= 3

Step3:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

So, Greatest Common Divisor of 423, 402, 56, 863 is 1
