Given numbers are 194, 685, 551, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(194, 685) = 132890
GCD(194, 685) = ( 194 x 685 ) / 132890
= 194 / 685
= 194
Step2:
LCM(1, 551) = 551
GCD(1, 551) = ( 1 x 551 ) / 551
= 1 / 551
= 1
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 194, 685, 551, 455 is 1
