Given numbers are 655, 785, 231, 217
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 785) = 102835
GCD(655, 785) = ( 655 x 785 ) / 102835
= 655 / 785
= 655
Step2:
LCM(5, 231) = 1155
GCD(5, 231) = ( 5 x 231 ) / 1155
= 5 / 231
= 5
Step3:
LCM(1, 217) = 217
GCD(1, 217) = ( 1 x 217 ) / 217
= 1 / 217
= 1
So, Greatest Common Divisor of 655, 785, 231, 217 is 1
