Given numbers are 756, 770, 563, 209
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(756, 770) = 41580
GCD(756, 770) = ( 756 x 770 ) / 41580
= 756 / 770
= 756
Step2:
LCM(14, 563) = 7882
GCD(14, 563) = ( 14 x 563 ) / 7882
= 14 / 563
= 14
Step3:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
So, Greatest Common Divisor of 756, 770, 563, 209 is 1
