Given numbers are 661, 511, 985, 893
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 511) = 337771
GCD(661, 511) = ( 661 x 511 ) / 337771
= 661 / 511
= 661
Step2:
LCM(1, 985) = 985
GCD(1, 985) = ( 1 x 985 ) / 985
= 1 / 985
= 1
Step3:
LCM(1, 893) = 893
GCD(1, 893) = ( 1 x 893 ) / 893
= 1 / 893
= 1
So, Greatest Common Divisor of 661, 511, 985, 893 is 1
