Given numbers are 205, 105, 220, 763
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(205, 105) = 4305
GCD(205, 105) = ( 205 x 105 ) / 4305
= 205 / 105
= 205
Step2:
LCM(5, 220) = 220
GCD(5, 220) = ( 5 x 220 ) / 220
= 5 / 220
= 5
Step3:
LCM(5, 763) = 3815
GCD(5, 763) = ( 5 x 763 ) / 3815
= 5 / 763
= 5
So, Greatest Common Divisor of 205, 105, 220, 763 is 1
