Given numbers are 194, 865, 644, 486
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(194, 865) = 167810
GCD(194, 865) = ( 194 x 865 ) / 167810
= 194 / 865
= 194
Step2:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
Step3:
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
= 1 / 486
= 1
So, Greatest Common Divisor of 194, 865, 644, 486 is 1
