Given numbers are 680, 209, 234, 550
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 209) = 142120
GCD(680, 209) = ( 680 x 209 ) / 142120
= 680 / 209
= 680
Step2:
LCM(1, 234) = 234
GCD(1, 234) = ( 1 x 234 ) / 234
= 1 / 234
= 1
Step3:
LCM(1, 550) = 550
GCD(1, 550) = ( 1 x 550 ) / 550
= 1 / 550
= 1
So, Greatest Common Divisor of 680, 209, 234, 550 is 1
