Given numbers are 664, 556, 843, 402

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

Apply this formula for all numbers.

Step1:

LCM(664, 556) = 92296

GCD(664, 556) = ( 664 x 556 ) / 92296

= 664 / 556

= 664

Step2:

LCM(4, 843) = 3372

GCD(4, 843) = ( 4 x 843 ) / 3372

= 4 / 843

= 4

Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 664, 556, 843, 402 is 1
