GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(523, 288) = 150624
GCD(523, 288) = ( 523 x 288 ) / 150624
= 523 / 288
= 523
Step2:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
Step3:
LCM(1, 869) = 869
GCD(1, 869) = ( 1 x 869 ) / 869
= 1 / 869
= 1
So, Greatest Common Divisor of 523, 288, 638, 869 is 1
