Given numbers are 685, 551, 176, 890
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 551) = 377435
GCD(685, 551) = ( 685 x 551 ) / 377435
= 685 / 551
= 685
Step2:
LCM(1, 176) = 176
GCD(1, 176) = ( 1 x 176 ) / 176
= 1 / 176
= 1
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 685, 551, 176, 890 is 1
