Given numbers are 831, 811, 511, 478
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(831, 811) = 673941
GCD(831, 811) = ( 831 x 811 ) / 673941
= 831 / 811
= 831
Step2:
LCM(1, 511) = 511
GCD(1, 511) = ( 1 x 511 ) / 511
= 1 / 511
= 1
Step3:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
So, Greatest Common Divisor of 831, 811, 511, 478 is 1
