Given numbers are 838, 688, 521, 511
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(838, 688) = 288272
GCD(838, 688) = ( 838 x 688 ) / 288272
= 838 / 688
= 838
Step2:
LCM(2, 521) = 1042
GCD(2, 521) = ( 2 x 521 ) / 1042
= 2 / 521
= 2
Step3:
LCM(1, 511) = 511
GCD(1, 511) = ( 1 x 511 ) / 511
= 1 / 511
= 1
So, Greatest Common Divisor of 838, 688, 521, 511 is 1
