GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 979) = 643203
GCD(657, 979) = ( 657 x 979 ) / 643203
= 657 / 979
= 657
Step2:
LCM(1, 543) = 543
GCD(1, 543) = ( 1 x 543 ) / 543
= 1 / 543
= 1
Step3:
LCM(1, 986) = 986
GCD(1, 986) = ( 1 x 986 ) / 986
= 1 / 986
= 1
So, Greatest Common Divisor of 657, 979, 543, 986 is 1
