Given numbers are 811, 143, 457, 284
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(811, 143) = 115973
GCD(811, 143) = ( 811 x 143 ) / 115973
= 811 / 143
= 811
Step2:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
Step3:
LCM(1, 284) = 284
GCD(1, 284) = ( 1 x 284 ) / 284
= 1 / 284
= 1
So, Greatest Common Divisor of 811, 143, 457, 284 is 1
