Given numbers are 811, 687, 143, 431
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(811, 687) = 557157
GCD(811, 687) = ( 811 x 687 ) / 557157
= 811 / 687
= 811
Step2:
LCM(1, 143) = 143
GCD(1, 143) = ( 1 x 143 ) / 143
= 1 / 143
= 1
Step3:
LCM(1, 431) = 431
GCD(1, 431) = ( 1 x 431 ) / 431
= 1 / 431
= 1
So, Greatest Common Divisor of 811, 687, 143, 431 is 1
