Given numbers are 538, 191, 647, 918
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(538, 191) = 102758
GCD(538, 191) = ( 538 x 191 ) / 102758
= 538 / 191
= 538
Step2:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
Step3:
LCM(1, 918) = 918
GCD(1, 918) = ( 1 x 918 ) / 918
= 1 / 918
= 1
So, Greatest Common Divisor of 538, 191, 647, 918 is 1
