Given numbers are 440, 806, 195, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(440, 806) = 177320
GCD(440, 806) = ( 440 x 806 ) / 177320
= 440 / 806
= 440
Step2:
LCM(2, 195) = 390
GCD(2, 195) = ( 2 x 195 ) / 390
= 2 / 195
= 2
Step3:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 440, 806, 195, 261 is 1
