Given numbers are 245, 217, 777, 881
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 217) = 7595
GCD(245, 217) = ( 245 x 217 ) / 7595
= 245 / 217
= 245
Step2:
LCM(7, 777) = 777
GCD(7, 777) = ( 7 x 777 ) / 777
= 7 / 777
= 7
Step3:
LCM(7, 881) = 6167
GCD(7, 881) = ( 7 x 881 ) / 6167
= 7 / 881
= 7
So, Greatest Common Divisor of 245, 217, 777, 881 is 1
