GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(558, 969) = 180234
GCD(558, 969) = ( 558 x 969 ) / 180234
= 558 / 969
= 558
Step2:
LCM(3, 257) = 771
GCD(3, 257) = ( 3 x 257 ) / 771
= 3 / 257
= 3
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 558, 969, 257, 805 is 1
